- Enable MSC4242 complement tests - Fix an issue which caused cascade rejections to not be applied to events in the /send_join response becau se we didn't remember in-memory which events were rejected. - Accept rejected events in the /send_join response, it gives us a bit of robustness at no safety cost. - Recalculate room state if backfilled events caused the state DAG fwd extrems to change. - Don't filter out already seen events from event_map, so the statement "the event_map is the complete stat e DAG" still holds. - Add validation to length of prev_state_events - Don't validate auth_events length for state DAG events as it is done too early, before we've had time to calculate the auth events (and validation is moot anyway given it isn't attacker controlled anymore) - Let backfilled events update state dag fwd extrems - Add test for edge case with backfilled state events
