press ESC again to interrupt doesn't work in tmux + ghostty (recent regression) #22629
Description
Description
When opencode is running, it says "press ESC again to interrupt". This has worked flawlessly for me since I've been using opencode until today. Now it does nothing.
My setup is macOS running GhosTTY with tmux, and opencode inside of that.
- tmux 3.6a
- opencode 1.4.6
- ghostty 1.3.1
If I use Kitty instead of ghostty, the problem does not occur.
If I use Ghostty without tmux, the problem does not occur.
This problem didn't occur in the last version of opencode I was running (I assume 1.4.5 but I'm not sure it wasn't an earlier version).
I'm not sure where the actual bug lies since there are 3 pieces of software involved, but starting here in opencode since this used to work and no longer does.

@FurryWolfX i was just about to try your suggestion, but first went through my reproduction steps... and to my surprise I CANNOT REPRODUCE THIS ANYMORE ;-;
Something is afoot, but I clearly didn't capture enough info in this ticket, so closing.
