Steps to reproduce

1. Reproduce Room appears unread when receiving hidden events - RR not sent #4947 but on a Space rather than conversational room

What happened?

What did you expect?

For me to be able to at least clear the stuck notification, or not receive it in the first place.

What happened?

There are no rooms under PS that are unread. It appears as though one of the subspaces or the space itself is "unread" for some reason.
