When I was playing multiplayer with one other person, I was trying to wear a mob head (all of them do the same including pumpkins) and when I wore them and my friend looked around my head would move along with his when I wasn't touching anything.

What I expected to happen was...:
I expected to just be able to look around.

What actually happened was...:
I see normally but when I went into third person my head was moving without me doing it.

Steps to Reproduce:
1. Put on either a pumpkin or a mob head
2. Be in multiplayer
3. Have someone look around.
