So this appears to be a new thing in A21 that is apparently supposed to automatically get a player unstuck if they get stuck. Was this added in the last update due to players getting stuck in doors, maybe? It sounds great in theory but it fails in actual use. It's one thing to have an option the player can use to unstick themselves but auto-unstick is very often a bad idea. In this case, I was mining and if I didn't have the mine shaft at least a couple of blocks wide, it would start bouncing me up and down while I'm trying to mine. That's a very bad system. I'm not posting it as a bug report because I think it's working as intended but I also think "as intended" is bad.
