Original Issue: It seems that the user list in chatroom is not really showing who is actually there. It seems to sometimes work and sometimes not. I haven't fully checked this yet on the code but wanted to confirm this ias an actual ssue first.
My guess is that this might have something to do with the node.js Drupal presence notification as opposed to actual presence. I'm not sure.

Revised Issue: After observing this on my site for some time now, it appears that the chatroom user list gets updated when a new users joins or leaves a chatroom. So it works fine for when a new users joins a chatroom (=user added to list) and when a users leaves a chatroom (=user gets removed from the list). The issue seems to occur when someone just enters the chatroom: it appears blank; as if new one is in the room.
