Items are moved above the player's hitbox when picking them up while swimming/crawling

The bug

When a player is picking up items while swimming, the items are moved above the players head. This looks somewhat weird and is also not the case when the player is not swimming.

I have not tested whether this is the case when flying with elytra as well, but I assume it is.

To reproduce

1. Enter a place that's 1 block tall
2. Enable F3+B
3. Drop an item
   → The item is moved above your hitbox when it's picked up
