Villagers have broken models in 1.13.x beta

Sleeping Villagers have incorrect animations/positions.

You can reproduce this bug easily, follow the steps:

1. Create world in creative mode.
2. Summon a villager.
3. Place a bed and do /time set night. You can see that the villager sleeping position is also incorrect.

I also attached pictures.
