What I expected to happen was...:
I was expecting to place objects such as crates, beds, and other floor objects onto carpets without it looking like they floating in the air.

What actually happened was...:
Carpets have an invisible layer height of a normal block so placing objects on top of carpets look like they floating in mid air

Steps to Reproduce:
1. Place any carpet down
2. and try place an object on top of the carpet
