(Bug?) Having Open Breakout rooms disables "Reactions" tab in Main Room

[NikkiR]

I tried to host a meeting where there were available breakout rooms for participants interested in a specific subject. The intention was to break up the conversations, while also making use of the MAIN room (where the primary conversation was going to happen).

However, having those open breakout rooms completely disabled the Reactions tab for all the participants (even Co-hosts) in the Main room.

Why is that? That doesn't seem like a feature to me, that seems more like a bug.
