(Not an actual chat room, a simulation of one)
I've noticed when you play this game, the chat suddenly breaks 10 seconds after you type in your name. (Chat messages suddenly become no longer underlined and no more new messages appear) But it seems to work when you dont enter your name.
Edited cause it's confirmed to be a Ruffle issue.
Tested with the latest nightly
It shouldn't break 10 seconds after entering in your name.
I'm seeing the same issue, I'll describe it in detail:
Still an issue as of the latest nightly.
