Bug Description

As the title says mobs spawn on clear leaded glass in my mob farm, but not on any of the other leaded glass blocks I tried so I'm quessing that it is a bug.

To give some more information, ghasts, zombie pigman andnormal pigman spawned on a layer of a full chunk of clear leaded glass in the nether.

How to Reproduce?

Make a platform of clear leaded glass blocks in the nether and wait for mobs to spawn.

Expected Behavior

Monbs shouldn't spawn on glass blocks.
