Hmm, this looks wrong too because makeMinimalChatInfo already adds member entries for DMs. Is the problem that FBChatResync.Members contains yourself, but not the other user?

Seems like neither are set and we fallthrough to makeMinimalChatInfo but that doesn't include user info, so the room is re-created with no profile on the other user. We also don't have any ghost for mautrix to pull the profile from.

I have not reproduced this directly, however.

User info is fetched separately if needed. It's only included in the member list if conveniently available
