I was doing stuff with my friend when I noticed that his elytra looked as if he was flying wierd. I was using no texture pack, and no resource packs. Also my friend was in split screen.

Steps to reproduce: Get an elytra and equip it. Then start walking around. Make sure you are the second person on split screen. 

Expected result: The elytra will look normal when walking.

Observed result: The elytra is in fly mode, even though they are walking or standing still.
