When 1 seconds was used it seemed to be overreactive.

The timeout will be configurable though
'peerDisconnectedThroughRtcTimeout' conference config option. It has
not been document in the public API on purpose.

'onmute'/'onunmute' event of MediaStreamTrack can be used to detect that
the remote user is having connectivity issues, because no video data is
received. We check if those are in sync with the signalling and if not
trigger connection interrupted updates with small delay.

The event is triggered when the notification about the user's connection
status change arrives from the JVB.
