Tested on main (c68752b)

Scenario 1

• User A joins room
• User B joins room
• User B starts typing
• -> User A sees no typing indicator, although startedTyping message is correctly received

Scenario 2

• User B joins room
• User A joins room
• User B starts typing
• -> User A now sees a typing indicator

From a quick look it seems that in scenario 1 the sessionId from User B is not correctly updated in the participant store, therefore participantsListTyping is not able to find participants that are typing. It seems to only work, if the session is active in the room already when joining, not when the session joins later on.
