In the "Overview" of some of the Stack Exchange chat rooms, the number of "all time messages" is shown for some of the room owners and not shown for the rest.
For example, let's take The h Bar:
Here I can see 83.8k for ACuriousMind and 19.2k for DavidZ, and nothing for the rest. For a similar example, check out the SO Python room. Is this a bug?
The room owners for which the message numbers are shown are exactly the ones that also appear in the list "currently in room" to the right.
Okay, that makes sense now. But I still don't understand why the "all time messages" should be shown only for "currently in room" ROs. Is there any justification for this? Or is this an unintentional design flaw?
