Rabbits get stuck inside the middle gap of shelves when jumping against them

The bug:
When a rabbit jumps against a shelf block, it can get stuck inside the middle gap.

Once trapped, the rabbit repeatedly tries to jump, bouncing in place until it eventually escapes.

Steps to Reproduce:

1. Place a shelf.

2. Spawn a rabbit next to it.

3. Wait for the rabbit to jump and collide with the shelf.

Expected Result:

The rabbit should collide normally and continue moving without getting stuck.

Actual Result:

The rabbit clips into the middle gap of the shelf and repeatedly jumps in place until it exits.
