When playing on a server, I noticed an issue with hit-boxes. The bug appears when you enable visual entity hit-boxes. When you enter 3rd person mode, your player's hit-box is above the player. The only part of the player that is in the hit-box is a small part of the head. This also appears above the player in the inventory screen.

Steps to Reproduce:
1. Press F3+B
2. Press F5 or open the inventory
3. Look above your player
