Update avatar follow message

I create a chatrooms with many user.
How I can create a message with user's avatar corresponding.
Now when I go to room and load older message, I can't not update avatar correct with user.

Reproduce the issue by creating a chatroom with many users, entering the room, and loading older messages. Trace how each older message is associated with its user's avatar. Done means avatars remain matched to the correct users when older messages are loaded.
