User avatars (and usernames) from previous posts not displayed when fetching room history (xmpp, matrix)
When a XMPP MUC or a Matrix Chat room (1:1 or chat room is basically the same in matrix), and the room history is fetched, the avatars from users and their usernames that made posts before you opened the chat room/MUC are not shown.
You only see avatars and the usernames in posts made after you opened the chat and maintained that chat open.
This is annoying as a user experience, because if you open a MUC or a matrix public room, and want to check the backlog you do not know which participant in the chat said what.
In this screenshot the red line indicates the first posts made after opening the MUC in Chatty and it fetched the room history.
