Offline label
We are sometimes suddenly shown as offline although our Language Lab tab is still open.
Tyler tried to send a message when Victoria was shown offline (but she wasn't); it didn't show as sent in his window. After opening the conversation again in a new tab, the message had been sent (though it didn't show as sent in the old tab; it was still in the text entry field). In the new tab, Victoria showed as online, and Tyler saw new messages from Victoria which weren't displayed in the old tab (where she still showed as offline).
We weren't able to reproduce the offline issue from last time. We speculated that it might have happened when @VictoriaDemierbe moved locations in her house, possibly causing a brief disconnection which, once restored, did not register in the student's chat window. We can't be sure yet that that was the cause of the appearing offline, but we'll try again to make it happen just to see if the connection restores correctly.
NB: Tyler did not try pressing refresh in the old tab. If it happens again, he'll try that.

So, when you say "offline", @VictoriaDemierbe, you mean the red dot next to the person's name, right? Maybe connected to #108: the red dot means the person is not seeing the conversation at that specific moment (I'm not sure what the idle time or "viewing another tab" duration is necessary for it to go back to red. @bridubois?). Maybe it's just that the red dot is misinterpreted as meaning "disconnected/offline", while it just shows the person is not in the window right now. We should discuss whether to explain or change the behaviour.
The delay is currently small, but we could increase it to ~60s maybe. I also gave two features that we could implement to avoid that in #108. In my opinion we should continue the discussion there.
