Stuck attendees in the conference room

[mekya]

If the attendee(stream) is not broadcasting state and terminated ungracefully due to crash, the attendee seems to be in the room. Unfortunately, its stream is stuck in broadcasting

Steps

1. Have 2 nodes in cluster mode
2. Install Circle
3. Join the room(test) as User1 and make sure it's connected to node1
4. Terminate the node1 unexpectedly with kill -9 and don't let it start
5. Close the tab for User1
6. Join the room(test) again as User2 and make sure it's connected to node2

Expected
Only User2 should be in the room

Actual
User2 and User1 seem to be on the participant list

The problem is that User1 stream is stuck as "Broadcasting" and it's listed as subtrack. Possible solution to check if the stream isStreaming as we do in the backends.
