Chat is stuck in "Running code" and I can't cancel it

I started this chat a while ago and returned to it now, but it’s stuck in an in-between state - even though I haven’t touched it for a few weeks, it still shows “Running code” and the cancel button doesn’t cancel that.

Seeing this too on a chat, with no fancy async stuff happening or anything. Looking into it…

Just deployed a fix, should work in a few minutes
