Summary:
Compound Creator collision is like a full block. It should have a void like Cauldron. This also includes the fact that blocks such as Torches, Redstone, Lanterns, Pointed Dripstone and others can be placed on the top and bottom side of the Compound Creator. Compound Creator should behave like Cauldron.

Steps to reproduce:

1. Switch on in the world of Education Edition.
2. Place Compound Creator.
3. Place blocks like Pointed Dripstone, Redstone, Lanterns, Torches on the top side.
4. Try to get inside the Compound Creator.

Observed results:
Compound Creator is like a complete block. It can be placed on any blocks and does not have a void like Cauldron.

Expected results:
Compound Creator will be like Cauldron. Blocks such as Torches, Redstone, Lanterns, Pointed Dripstone will not be placed on its top/bottom side. It will also have collision like a Cauldron.

Original Description:
Despite having the same model as cauldron, you can place torches on top of this block which kind of just floats there.

You can not place torches on top of cauldron (because it is just air) but you can with education edition cauldron which is weird
