When the player is flying into a block, the top part of their model will be inside the block, and only a small portion of their feet and the wings will be visible.

Steps to Reproduce:

Vertically:

1. Equip an elytra
2. Fly into water (this is to prevent the player from standing up when touching the ground)
3. With the elytra active, swim downward

Horizontally:

1. Equip an elytra
2. Build a wall of blocks (recommended to use transparent ones)
3. Fly towards/into the wall

Expected: The player's model would not clip inside of blocks.
Observed: The player's model clips inside of blocks, only their feet and the end of the wings will be visible.
