Evoker/villager/witch robes don't render the last two rows of pixels

Related to MC-53312
Villagers that wear robes, evokers, and witches have the mesh for their robes cut off 2 pixels above where the texture ends (the robe texture is 20 pixels tall, only 18 show in-game).

How to Reproduce

1. Spawn some villagers, evokers, and witches.
2. Pay attention to the bottom part of the robe.
3. Compare it with Java's counterpart in the latest snapshot.

Observed Result
The last two rows of pixels on the robes are cut off.

Expected Result
The last two rows of pixels should show in-game like in the recent Java snapshot.
