"MForbidden: user does not belong to room" on messages, reactions, read receipts sent by Facebook user with custom nickname
I've observed that messages (of any type, apparently) from a Facebook user who has a custom nickname set aren't bridged to Matrix, claiming that the Matrix ghost user doesn't belong to room. However, those users are correctly shown in people list in Element.
Bridge version: 0.4.0 Homeserver: Dendrite 0.8.1

There were no errors in homeserver logs.
A couple of observations:
- issue doesn't occur in private chats
- issue isn't present when Synapse 1.56.0 is the homeserver
