Gravity Effect Blocks Going Through Wall Placed Items

When doing some bug testing I found something that I would class as a unintentional bug. When a gravity effect block falls next to a wall with a wall placed item, it goes right through.

 

How To Replicate

1. **Build a pillar.
2. Place wall item (E.g. Button, Torch etc).
3. Place sand one block or more above the torch and watch it go through.
