Spawning a villager on a flat stone freezes all blocks' and entities' activity

I was playing on the stone platform. But the issue is that if I spawn the villager, every blocks' and entities' activity is frozen. This observation might be the best way to observe when creating a super flat world using 'The Void' type.

I guess that there might be no path limit. Can you fix the bug to limit villagers from generating pathways?
