Cats sitting on chests block the chest below the chest the cat is on (so 2 chests)

If a cat sits on a chest then the chest is blocked, this is normal behavior, but it also affects the chest under the one the cat is sitting on, so 2 chests are affected.

 

Steps to reproduce:

1. Place a chest
2. Place a chest on top of the first chest
3. Put a tamed cat on top of that
4. Notice both chests are affected

Expected Behavior:

Only the chest the cat is sitting on would be affected, not both.
