There is a weird bug in chat. Try this:
- Post a message,
M1. - Post another message,
M2. - Delete
M2. - Try hitting the up-arrow key.
I'd expect still to be able to navigate to M1 to edit it, but it doesn't seem to work. But wait, there's more!
- Post another message,
M3. - Try hitting the up-arrow key.
Now it works again, but more importantly, I can now navigate through the deleted message. In fact, I can even try to edit the deleted message, although that edit will be rejected.
This behaviour seems inconsistent, and moreover a bit inconvenient, since I have to use the mouse if I want to edit M1 in the first case. Just imagine the pain.
