Big Dripleaf's "leaf" when tilted has a parallelepiped/pipelined model instead of it being a rotated model/texture

What happened
When the "leaf" of a Big Dripleaf tilts downward, the tilted "leaf" has a parallelepiped/pipelined model. This doesn't happen on Java Edition, making this a parity issue.

Steps to Reproduce

1. Place down a Big Dripleaf

2. Make a player stand on the top / drop an item on the top

• The tilted "leaf" has a parallelepiped/pipelined model

Observed Result
The tilted "leaf" has a parallelepiped/pipelined model, making this parity

Expected Result
The tilted "leaf" is a actual rotated model/texture
