Another variant of this: typing numbers on a single line.

Input: 1. 2. 3. 4. 5. 6. 7. 8. 9.

Rendered in the user bubble: 1. b. iii. iv. v. vi. vii.viii. ix.

Each N. opens a nested ordered list, so the levels switch to letters and then roman numerals. The values are technically right, but it's far from what was typed. The vii. and viii. markers also overlap because the marker gutter is too narrow for long roman numerals.

The literal-numbers approach in #8554 (decimal markers for nested lists in user messages) would cover this case too.

Windows 11, desktop.
