Steps to reproduce:
1. Sprint-swim under water
2. Hit an entity while holding down the sprint button
(You should see your character canceling the sprint-swim only for less than a second)
3. Your Hitbox should now behave like you are standing.
4. Can be cancelled when you stop swimming
In this bugged state, you get stuck when swimming under a block, because your Hitbox is bugged into the block.
You can also swim close to the surface to regain air, because the Hitbox of your head is above water.
Pressing F3+B (Keybind to make Hitboxes visible) won’t show the desynced Hitbox.
