Zombie Villagers with bugged textures

The Zombie Villagers are with a buggy texture, with missing parts of their body.
I have a screenshot, taken on Minecraft, to show off the bug.

What I expected to happen was...:
The Zombie Villager texture should not be bugged as it is now.

What actually happened was...:
It have a very buggy texture, with hat missing and weird hands.

Steps to Reproduce:
1. You need to find or summon a Zombie Villager.

After doing so, i will see that the Zombie Villagers are with a bugged texture.
