I can\'t close private room if other user closes his windows

[decola]

Let's consider this case.

I open a private room with user A.
User A closes his browser,
I can't close private room.

I think this is a bug.

I just tried this with the demo on this site and was able to duplicate the problem. Unable to close a private chat tab if the other user has closed their session.

Not the end of the world, but worth a look.
