Count of people besides the People room settings entry is incorrect after joining room

[dkasak]

Steps to reproduce

Immediately upon joining a room, the count of people besides People in room settings can be wrong. Actually entering the People menu shows the correct member list, but the count outside is wrong until the app is restarted.

In the above situation there were actually 7 people in the room. Unfortunately I didn't reproduce this myself and the affected person cannot rageshake so there will be no logs.

Outcome

What did you expect?

The correct count to be displayed.

What happened instead?

The incorrect count was displayed.

I wonder if this is related to/caused by the same thing as #4236

Maybe tangentially, I do think it would be prudent for the app to render some kind of indication that the user count in the room is unknown (spinner, or ?, or something) until the join is complete and the full state of the room is resolved on the homeserver

I don't think so, the value we use there comes from a completely different source, AFAICT. And if I'm not mistaken, this value is only updated here when we receive the room from sliding sync, then it's serialized and deserialized when needed.
