Zombie Horses and Zombie Nautiluses still burn in sunlight even when you put armor on them.

• Steps to reproduce the issue

Spawn a zombie horse or a zombie nautilus outside of water, put armor on, and boom! The armor has no effect on the mobs.

• Expected result

The mobs are immune to sunlight damage as long as they wear their armor.

• Actual result

The mobs burn to a crisp, even with a horse or nautilus armor.
