[MC-134360] Mobs do not suffocate in half-aligned "double slabs"

To the right is a true double slab, to the left is a bottom slab on top of a top slab. The suffocation behaviour is inconsistent; one would expect the creeper on the left to also be taking suffocation damage.

AFAIK this is intended. Mobs only suffocate in solid blocks, double slabs are solid, half slabs are not even if they are arranged like this.

I believe that @caucow is correct

Works As Intended I believe. The two previous comments are correct.

Leaving open for mojang to decide (they could make half slabs suffocate as well).

Not only is it not fixed in 20w29a, double half slabs don't suffocate mobs too.
