Parrots' bodies disconnect from their legs while dancing

The bug

While dancing, parrots' bodies can completely disconnect from their legs.

How to reproduce

1. Find/spawn a parrot (spawn eggs, commands, or just naturally generated)

2. Tame it (by feeding it seeds)

3. Sit the parrot down on top of a jukebox

4. To the side of that block, dig down two blocks, then place a bottom slab

5. Stand on the bottom slab

6. Insert a music disc into the jukebox (I recommend chirp!)

7. Notice how the parrot's body disconnects from its legs while it is dancing
