- History visibility checks MUST NOT be applied to sticky events. Any joined user is authorised to see sticky events for the duration they remain sticky.
I think sticky events in this situation will never come down the timeline section of sliding sync, but I need to confirm that. In the Synapse implementation it looks like Sliding Sync only shows events since you joined the room.
