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

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.
