[BUG] Incorrect slash command suggestion on v2.0.30

What's Wrong?

When I type /context, Claude Code suggests/highlights /compact instead – I almost accidentally compacted my session, which I very much did not want to do!

In this screenshot, all I've done is typed /context – I haven't hit any of the arrow keys to adjust the highlighted command. If I hit enter, I will select the wrong command.

What Should Happen?

Claude should highlight the slash command that matches what I've typed, not some other one.
