That also happens with the /summon command and after relog

Affects 1.21.9-1.21.11

I can observe this with /summon and natural spawns, so I’m updating the title

This behavior was introduced in 25w31a, the first snapshot for 1.21.9. I’ve added this to the description.

In that version, it seemed to affect zombie villagers in any biome, but only with spawn eggs. /summon, spawners, and natural spawns seemed unaffected.

In 26.1-snapshot-1, the behavior changed. Since then, only plains zombie villagers are affected. Zombie villagers in other biomes work correctly. However, more than spawn eggs are affected now. All forms of spawning plains zombie villagers are affected.
