Observe that the invite they receive is misnamed and just says it came from you, rather than being an invite to an existing DM.
Outcome
What did you expect?
The server should hopefully send us enough info about the invite in the invite state to be able to synthesise a consistent room name. If it doesn't, it should.
What happened instead?
If Alice invites Charlie to her existing DM with Bob, Charlie's EI sees an invite from Alice to a room called Alice, not a room called Alice & Bob.
