Joining and leaving a room in the same batch should result in a full state sync (SYN-514) #1413
Description
This issue has been migrated from #1413.
Submitted by @richvdh:matrix.org
If a user joins a room, then immediately leaves it, so that /sync returns both events in the same batch - should /sync return the complete state for that room (as it does normally when joining a room)?
