Sulfur cubes can clip into walls and suffocate when they grow up

When a Sulfur Cubes grows up and is near a wall, it’s possible for it to clip into the block and suffocate if it’s a full solid block. When I tried it with fences, the Sulfur Cube clips through the fence and is able to get away.

Steps to reproduce:
1. Make a small area and spawn a baby Sulfur Cube inside it.
2. Wait for it to grow up.

Expected result:
Adult Sulfur Cube stays within the area and does not clip into walls.

Actual result:
The adult Sulfur Cube clips into walls and suffocates.
