The new Rabbit model cannot turn its head to look at things, unlike the old model

The Bug:
Before this snapshot, the old Rabbit model use to be able to turn its head ambiently, especially to look at the player, as seen below

With the new model and animations as of 26.1 Snapshot 2, they are no longer able to, as seen with these screenshots:

The new rabbits seem so lovely otherwise, and the old model was able to move its head, so I expected this to be possible
