Snow Golems' Heads Rendered Sideways

Snow Golem's Heads are displayed sideways. Instead of the pumpkin "face" being on the same side as the button's on the body of the Snow Golem, the "face" is on the Golem's left side. The button's still face the correct direction for both movement and throwing snow balls. Orientation of the Golem relative to the world (north, south, east, west) does not matter.

To reproduce:
Create a snow golem in a new world in a biome where snow golems can survive. It's will be on sideways.
