When going through a Nether portal, either going or returning, the armor icons disappear. The armor its self is fine, however the icons just aren't shown. They only return after logging in and out of a world.

What I expected to happen was...:
I thought they would just be there like always, thought I wasn't wearing armor

What actually happened was...:
I was still wearing armor, it just wasn't displaying it

Steps to Reproduce:
1. Put armor on in either the Nether or the normal world.

2. Build and light a Nether portal, then step into it

3. After you teleport, the armor icons should disappear

(To make them return)

1. Save and Quit out of the world
2. Go back to the same world in the same version
3. The icons should return
