Iron Golems can spawn on transparent blocks

Iron Golems can spawn on transparent blocks like glass or leaves. This was not the case in 1.19.4.

Screenshot shows Iron Golem spawning on glass block next to my iron farm. I watched the farm for a while and the Iron Golems spawned on different glass blocks all around the farm.

To reproduce

[media]
  1. Create a glass flatland world

  2. Build a stone platform for iron golems to spawn on

  3. Place three beds and summon three villagers

  4. Set the time to night briefly, to let the villagers sleep in the beds

  5. Summon a husk

  6. Wait for the villagers to spawn in an iron golem

Observed behaviour

The iron golems often spawn on top of some glass blocks.

Expected behaviour

The iron golems should only be able to spawn on the stone platform, as is the case in 1.19.4 and below.

This is not a duplicate. Iron golems spawning partially inside glass is one thing. Since 1.20 prereleases, iron golems are spawning completely on top of glass with no non-glass blocks nearby.

Thank you. I can confirm that this changed at some point since 1.19.4

This has probably changed in 23w16a material refactor. Iron golem spawning previously used materials, if I remember the gnembon video correctly.
