Set difficulty level to peaceful and spawn a Piglin in the Overworld.
Expected result: in a few seconds, the Piglin despawns, as the Zombified Piglin is not allowed.
Actual result: the Piglin does not zombify, and stays forever.
This seems related with the resolution of MC-307951, now the piglin does not make noise, but does not despawn.
