Problem

Completing a list marker inside existing composer text left a paragraph on screen while saving list Markdown. Rebuilding the draft then changed its appearance. Reproduces #22989, mirrored as #22997.

Change

Choose option (a): make the editor match its Markdown, preserving the expected bullet and existing draft-rebuild behavior. A ProseMirror append transaction normalizes only changed, unindented top-level paragraphs. It mirrors existing bullet (-, *, +), ordered (1., 1)), and dash-task markers, preserves marker spelling and formatting, and groups conversion with the edit for undo. Styled literal markers, code, existing list items, and blockquotes are excluded. Composition waits for the next non-composition transaction.

Verification

Superseded: the evidence in this section (head 9c3c3acbc6) is replaced by Evidence below, captured on the merged head.

Evidence re-captured as narrated before/after recordings per EVIDENCE.md (merge-base 680152e27b vs head 9c3c3acbc6). 58 of 70 matrix rows recorded as four-cell grids (232 of 280 cells). Recorded interactions are not all passing proof; timing is not frame-identical.

Exhaustive per-row appendix and repair ledger · Fixture matrix · Proof audit pass 2: INSUFFICIENT (C1, C2, A1, I1, V2–V9 missing; P1, H1, E1 contradict the matrix expectation on both revisions; R1, V1 incomplete; W1 leading-Tab divergence unexplained).

Representative row L1: type -existing text, Shift+Enter, type second line, Ctrl+Home, Right, Space, Ctrl+End. After converts the first line to a bullet following Space; before stays literal; second line survives. Times are approximate dispatch times (about 0.5 s skew in desktop light).

Environment: Linux x86_64, Chrome 154, DPR 2, zoom/text scaling 100%, root 16px; 1440×900 / 390×844 light/dark. Real app, matching isolated .t3 seeds, live clock. Recordings are about 4.3 fps, so sub-250 ms steps cannot be distinguished.

What else changed: helper + focused tests only; gutter/prefix/caret/wrapping changes. Capture noise: provider-update toasts, relative ages, caret blinking, shell status, environment IDs. An independent F1 rebuild matched the published composer within 15 pixels (caret).

Unverified: C1, C2, A1, I1, V2–V9 (IME and genuine contextual prerequisites unavailable; other sequences missed the capture cutoff). P1, H1, E1 contradict the matrix expectation on both revisions. R1 palette/keybinding and V1 full collapse/expand remain incomplete. W1 leading-Tab divergence between revisions is unexplained. L5 390-dark has a 2:19 stall.

Capture: Codex gpt-6.1-sol; proof audit: Claude Opus 5.5.

Model/harness: GPT-6.1-Sol via Codex in T3 Code; adversarial code and evidence review by GPT-6.1-Sol/Codex and Claude Opus 5.5/Claude Agent.

Evidence

Before = main 8d3b061121 · After = 9096191f30 (main merged into this branch; the later head d339b79358 adds only the driver script). Matrix re-derived from the diff: matrix.md (16 fixtures). Capture index with per-step timestamps: index.md. Driver: scripts/evidence/drive-composer-list-markers.mjs.

Partial. The capture VM was at load ~20, so only F1–F5 have before/after recordings. F9–F12 have After only, and the other rows were not captured (see the verification log).

The matrix corrects the earlier audit's contradictions. On both revisions, typing *, +, 1., 1) or - [ ] and then Space in front of existing text already converted through input rules, so old L2–L5 showed no difference. P1/H1: a real paste parses Markdown blocks. E1: Shift+Enter on - exits the empty item. W1: Tab moves focus out of the composer, so that divergence was a capture artifact. F2–F4 cover the paths only the plugin handles: the marker character typed last, an ordered start number, and a Delete that completes the marker.

Environment: fs-09, Linux x86_64, Playwright 1.60 Chromium headless shell, DPR 1, 1440×900, colorScheme: light, rich text on. Two vp run dev servers seeded with identical isolated .t3 data from vp run migrate-dev-db; clock frozen for stills.

What else changed: only the git panel, which reflects each checkout's state rather than the PR. Before is a detached checkout, so it shows "Select ref" and +0/−0; After shows the branch and its diff counts. No toasts. On both revisions, Shift+Enter at the start of a line stalled about 71 s under load.

Verification log
  • Proof audit pass 1 (Claude Opus 5.5): matrix derived, 16 fixtures. Proof audit pass 2 not run: the 120-minute budget ran out after the capture. The capture is incomplete, so the current verdict stays INSUFFICIENT.
  • Tests on 9096191f30: vp test run src/composer-block-shortcuts.test.ts src/composer-rich-text-doc.test.ts, 280/280 passed.
  • CI: pending on d339b79358 at the time of writing.
  • Unverified rows:
    • F6–F8, F8-E1: the app sat on the splash screen for more than 240 s on both revisions (VM load).
    • F9–F12 before: the run was cut off when the servers stopped.
    • F10d, F11c, F12b–d, F13: clicks timed out under load.
    • F14, F16a, F16b: not reached.
    • F16c, F16d: need a live pending question or a disconnected composer.
    • 1440 dark and all 390 captures: not reached.
    • F15 (IME): CDP composition events do fire, but in a smoke run that was not uploaded, - 日本語 stayed literal after End. End was probably a no-op because the caret was already at the end, so the run sent no transaction. Re-run it with a real follow-up edit or caret move.
  • Model/harness: evidence lead, proof audit and capture by Claude Opus 5.5 via Claude Agent in T3 Code.

Walkthrough

The rich-text composer now normalizes eligible list prefixes in changed paragraphs. The added tests cover marker conversion, list merging, composition, history, and editor behavior.

Changes: Composer list normalization

Layer / File(s)Summary
List normalization plugin
apps/web/src/composer-rich-text-doc.ts		The bullet-list extension registers a plugin that converts eligible, changed top-level paragraphs into lists. It defers normalization during composition, handles history transactions, and joins compatible neighboring lists.
Normalization tests
apps/web/src/composer-block-shortcuts.test.ts		The test helper initializes and cleans up a headless editor. Tests cover marker conversion, exclusions, formatting and caret preservation, composition, history, and changed-block handling.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Suggested reviewers: chrisdeeming

Merge Risk: External image Low · up to 2f105

Some list markers entered after formatting may remain plain text until the draft is rebuilt. The issue is narrow and does not prevent merging, but it warrants follow-up.

Join compatible adjacent lists after wrapping.

tr.wrap creates a new list around the paragraph, but this path does not merge it with an adjacent compatible list. The serializer emits adjacent list nodes as consecutive Markdown items, while buildTiptapContent groups items with the same listKey. The editor can therefore differ from the document rebuilt from its Markdown.

Join only when the list-grouping keys match. A node-type-only check would incorrectly merge lists that use different bullet markers, such as - and *.

533This is a core module of ProseMirror. ProseMirror is a well-behaved rich semantic content editor based on contentEditable, with support for collaborative editing and custom document schemas.
534
535This module exports the editor view, which renders the current document in the browser, and handles user events.
536
537The project page has more information, a number of examples and the documentation.
538
539This code is released under an MIT license. There&#39;s a forum for general discussion and support requests, and the GitHub bug tracker is the place to report issues.
540
541We aim to be an inclusive, welcoming community. To make that explicit, we have a code of conduct that applies to communication around the project.

181 ## 1.42.3 (2026-08-25)
182
183 ### Bug fixes
184
185 Don&#39;t set `contenteditable=false` on widgets that already have a `contenteditable` attribute.
186
187 Fix a bug that broke pasting when there was a default trusted type policy defined without a `createHTML` function.
188
189 Run attribute validators on attributes provided via slice context in clipboard content. This closes an XSS vulnerability (found by Pedro Paniago).
190
191 ## 1.42.2 (2026-07-24)
192
193 ### Bug fixes
194
195 Enable a workaround for backspace not taking effect on Android for Firefox as well as Chrome (for which it already kicked in).
196
197 Work around the situation where Chrome/Webkit replace a node&#39;s content DOM with a completely different element.
198
199 ## 1.42.1 (2026-07-11)
200
201 ### Bug fixes
202
203 Don&#39;t scroll to a bogus position when trying to scroll an element that has no layout into view.
204
205 ## 1.42.0 (2026-07-01)
206
207 ### Bug fixes
208
209 The clipboard content parser now inlines simple styles defined in the pasted HTML before parsing it, since some applications output their styling that way.
210
211 ### New features
212
213 Mark views now also support an `update` method.
214
215 ## 1.41.9 (2026-06-10)
216
217 ### Bug fixes
218
219 Allow triple-click drag selection.
220
221 Adjust an existing workaround to work around the fact that Chrome no longer fires key events for backspace during composition.

Flush pending normalization when composition ends without a state transaction.

listNormalizationPlugin retains positions for composition-tagged transactions, but it only processes them during a later appendTransaction call. ProseMirror can finish composition without dispatching a transaction when the DOM and selection are already synchronized. In that case, the pending paragraph remains literal after composition ends.

🟡 Medium evidence/drive-composer-list-markers.mjs:73

When --storage-state contains an explicit appearance that differs from --theme, the capture uses the saved app theme, so --theme light can produce dark artifacts labeled light. The colorScheme setting only controls the browser preference, and useTheme honors the saved explicit mode; set or validate the app appearance before capturing.

🟡 Medium src/composer-rich-text-doc.ts:646

Shift-Backspace cannot undo a list input rule: undoInputRule() restores the literal prefix in a non-history transaction, and this normalizer immediately wraps it again. Exclude input-rule reversal transactions from normalization, not just history transactions.

No longer relevant as of 2f1053ae6ef0f80aa62461f184c02972c2ad16f4

The automated pipeline stopped on this pull request and will not merge it:

these checks fail on 89b7b5234a, also when run again: Check, Test Web, and the rework changed nothing:

No code change. The only failing test in Test Web is in apps/web/src/components/RightPanelTabs.browser.test.tsx (the flick/edge-swipe case, navigateHistory called 0 times). That file is outside this PR, which only changes composer-rich-text-doc.ts and composer-block-shortcuts.test.ts. The test fails the same way on a clean origin/main checkout (c82e1ba515, 2 of 2 runs) and on this branch (3 of 3 runs). Both RightPanelTabs files were last changed on main by #33396 (11611419f3), which reached this branch through the earlier main merge. 'Check' only fails because it requires every other job to pass, and Test Web was the only one that failed. Per the brief, a failure that also happens on origin/main gets no change here; it needs a fix on main, after which re-running CI or merging main again should clear both checks.

It stays open for a person to finish or close.

🟠 High src/composer-rich-text-doc.ts:682

Editing the literal paragraph * * at its start to produce * * * wraps it as a bullet list, but buildTiptapContent restores the same Markdown as a horizontal rule, so the editor content changes after draft restoration. parseListPrefix accepts thematic-break syntax here without the horizontal-rule check used by buildTiptapContent; exclude horizontal-rule lines before wrapping them.

With rich text enabled, type -get md, press Shift+Enter, type second line, insert a space immediately after the first dash, then click the second line. Blur the composer for the still.
