## Message

```
Clip flex editor blocks to the text viewport (#56549)

Resolves https://github.com/zed-industries/zed/issues/56518

This diff fixes code lens decorations continuing to paint into the
gutter when the editor is horizontally
scrolled. Code lens entries were rendered as flex editor blocks with
explicit gutter padding, which allowed
them to bypass the text viewport clipping used by content-only blocks.

With this change, code lens entries render as spacer-style custom blocks
instead. Spacer blocks already
scroll with buffer content and paint through the text-side mask, so the
code lens padding can be relative to
the editor text area and decorations clip at the left edge of the
viewport.

Release Notes:
- Fixed code lens decorations painting outside the editor viewport when
horizontally scrolling.
