Hey, thanks for the report and the video. This is a known issue with undo in inline diff, and the team is aware.

As a workaround, try undoing with Ctrl+Z in the editor, or use undo in the chat panel. Those use different mechanisms and aren’t affected by this bug.

The team’s aware of the issue, and your report helps with prioritization.
