Momentum cancels during sprint-jump hits

Since 1.21.60, i have noticed an annoying momentum cancel while fighting mobs and players. If you sprint jump and hit another entity whilst airborne, your velocity gets canceled. This happens on both realm and worlds.

How to reproduce
1) Spawn an entity (any entity) or get another player to join a realm or world.

2) Sprint jump and spam whilst hitting.

Effects
This makes all player versus player game-modes and even just casual survival very unplayable and unpredictable.

Furthermore, this seemed to kill the competitive community and has frustration for owners of player versus player servers.
