Missing test for issue with Firestore docs moving outside of replication scope #7371

[pubkey]

I understand the problem.
But I see no way to fix this on the RxDB side atm. If there is no more permission to the doc, the sync will not know about the move-out-of-scope change to that document.
Atm docs are expected to either stay inside or outside of the scope, not change that.

This should be fixable, because Firestore sends a 'removed event', RxDB just needs to process that.

https://firebase.google.com/docs/firestore/query-data/listen#view_changes_between_snapshots
shows an example how to correctly process these changes

If a document moves out of the replication scope because it no longer matches the filters, a 'removed' event is received by Firestore client.
I have verified this myself with my application.

I'll check if I can make the necessary modifications to the Firestore Replication plugin, but I don't know if I am sufficiently qualified, will keep you posted
