Describe the bug / provide steps to reproduce it

When using Zed to edit Gleam code, every now and then, Zed editor will add back in deleted text on save. (I do have the format on save option on.)

Unfortunately, I cannot reliably reproduce this bug. It will randomly happen every 10 minutes or so when actively coding. I did get a video of the behavior though.

Other odd things have happened on save as well, like a section of code gets stuck in where my cursor is. Unfortunately, I was not able to get a video of this behavior.

Zed Version and System Specs

Zed: v0.170.1 (Zed)
OS: Linux X11 ubuntu 22.04
Memory: 22.7 GiB
Architecture: x86_64
GPU: AMD Unknown (RADV RENOIR) || radv || Mesa 23.2.1-1ubuntu3.1~22.04.3

If applicable, add screenshots or screencasts of the incorrect state / behavior

Here's what I'm doing in the video:

1. Highlight the first line.
2. Press "delete"
3. Save the changes

After save the text pops back in.

If applicable, attach your Zed.log file to this issue.

This is the section of the log that is written when I take the action described in the video section.
