Fixes MC-156980 and MC-136367, allowing the player to exit boats without getting stuck.
MC-156980 refers to the scenario where the player walking on top of a boat causes their position to get continuously reset, requiring breaking the boat or jumping off to escape.
MC-136367 is about how a poor fix to MC-1489 made dismounting vehicles place you on top of or inside of them instead of to the front or side.
