I'm not sure what triggered this - no precise STR.

An XMPP conversation tab was open and non-empty. I was switching between tabs and sending messages, i.e. nothing unusual, and noticed something was wrong when the open tab had the red unread flag set despite there being no unread messages, and kept it even when switching between tabs.

Things normalized after new messages arrived.

Now also reproduced this by opening two chats from hold by clicking on both unread counters very quickly. It doesn't happen every time, so there is probably a race condition involved.

I wonder if this is the tabbrowser equivalent of bug 954935 (bio 1502) and/or bug 954646 (bio 1214)...

Do you still see that?

Haven't seen this in a long time, and I suspect various tabbrowser changes and fixes around this may have taken care of it.
