Player no longer moves slightly when jumping with horse, mule, or donkey

Previously, when the player riding a horse, mule, or donkey, and then press the jump button, the player would move slightly to the back to prevent the player camera from clipping with the mount, but this is no longer the case anymore.

Steps to reproduce:

1. Tame a horse, mule, or donkey

2. Equip it with a saddle, and then ride it

3. Press jump

4. Observe

Expected results:
Player move slightly to the back, matching previous version and Java Edition.

Observed results:
Player does not move at all, cause the player camera to clip with the mount.
