## Message

```
editor: Use `em_advance` everywhere for horizontal scroll position computations (#33514)

Closes #33472

This PR fixes some regressions that were introduced in
https://github.com/zed-industries/zed/pull/32558, which updated the
editor scrolling to use `em_advance` instead of `em_width` for the
horizontal scroll position calculation.
However, not all occurrences were updated, which caused issues with wrap
guides and some small stuttering with horizontal autoscroll whilst
typing/navigating with the keyboard.

Release Notes:

- Fixed an issue where horizontal autoscrolling would stutter and indent
guides would drift when scrolling horizontally.
```
