Members list not updated while room details are opened
In the same case as When kicking a member from their profile, we sh... (#1459 - closed), I then reinvited the member without closing the room details. When I went back to the members list, I noticed that the user was still in the list of joined users, and the button for inviter members had not shown up.
This seems to indicate that changes in the members list did not update the UI. Closing the room details and reopening them showed the proper UI, with the user appearing in the list of invited users.
