Enqueue replay record/playback until next frame (#15751) 
* Enqueue replay record/playback until next frame

This fixes a bug where stdin commands activated via polling would
trigger replay record/playback in the middle of a frame, then input
checking would pull from them before the next frame came around---it
only makes sense to change the active replay in between frames, not
during them.

* fix comment syntax
