Steps to reproduce

1. create a dm room
2. give the room a name
3. change the room name to empty. (remove the name and click save) (or set the state event manually)
4. the m.room.name state event content will be {name: ""}
5. check the room name and the room list (you will see what is presented below)

Outcome

What did you expect?

If Alice and Bob are the other participants in the room, the name shown in the client should be "Alice and Bob".

For reference, I expect this behavior because https://spec.matrix.org/unstable/client-server-api/#mroomname says that empty name fields should be treated the same as if no name was ever set.

What happened instead?

The name is empty:
