[Bug] Inaccurate Profile Picture Thumbnail Across Chat Rooms

When a user updates their profile picture (PFP) in one chat room, the visual thumbnail in previously visited rooms may not reflect the change. For example, if the user selects a “happy” PFP in both Room A and Room B, then switches to a “sad” PFP while in Room B, returning to Room A will still show the “happy” PFP in the UI.

Despite this, the system actually uses the updated “sad” PFP in Room A as well. This inconsistency between the displayed and actual PFP may cause user confusion.
