Steps to reproduce

1. User A write a message
2. User B react to the message

Expected behaviour

User A sees the reaction

Actual behaviour

User A sees the reaction only after the 0-30s of the chat polling pass. This is some what a performance optimisation, but it can be totally unexpected in this case. But if otherwise 70 people react 70 people reload the chat 70 times => 4.9k requests...
Might not be solvable for now, but want this to be documented at least

Talk app

Talk app version: master

Similar to typing indicator we could send a signaling message to the active participants in the room when adding/removing a reaction. Limiting it to external signaling should have no big performance issue and would not increase the load on the NC side

Yeah can also just close it and it comes when all chat messages come via HPB
