Player falls into floor and crouches when closing a door on the same block as player

If you open a door, stand on the spot where the door would be if it was closed, then close the door, it forces the player into the ground. I could easily reproduce it by doing what I described. It also works with fence gates and trap doors. Another thing that happens is the player seems to go into the swimming animation while in the floor, at least with trap doors it does.
