Opening a room will cause the usernames (in view?) to be loaded and resolved. The room list should probably do the same and not wait for the room to be opened to resolve the user's name.

In this example, watch the username of mscbot in both the room list before opening the room, after opening the room, then finally again when returning to the room: list.https://github.com/user-attachments/assets/87a468ac-424f-442f-ba31-69787f925e54
