Wrong hitbox and stuck in crouch mode when in door

Very similar to MC-166903 so I'm not sure if it is a duplicate.

How to reproduce:

1. Place a door
2. Crouch
3. Close door so it goes into your hitbox

Observations:

1. When releasing crouch key, view stays the same
2. When pressing F3 + B and F5, you can see that the player is standing but the hitbox is that of a player who is crouching
