Sulfur Cube interactions are not symmetrical

Hitting a Sulfur Cube from the exact same angle, relative position and distance in different cardinal directions will yield different results.

Steps to Reproduce:

1. Place a Sulfur Cube at the center of a short pillar

2. Feed it a block

3. Hit it at the very bottom from different directions

Observed Results:
The Sulfur Cube may be pushed away, or even pulled close depending on the direction.

Expected Results:
The Sulfur Cube is always pushed away, and always at a consistent direction.

Screenshots/Videos attached: Yes

Notes: Even hitting the center will show a little directional bias.
