Villager throws IllegalStateException: World mismatch when entering Nether Portal on Folia

Expected behavior

The Villager should safely teleport to the Nether, similar to other entities or players.

Observed/Actual behavior

The server throws an exception and the Villager fails to teleport:

No response

Reproduce on Folia 1.21.11 with a Villager entering a Nether Portal, then trace the async path through NetherPortalBlock.portalAsync, PortalProcessor.portalAsync, and Entity.portalToAsync. Compare the Villager construction in Entity.transformForAsyncTeleport with the World mismatch stack in Villager.makeBrain. Done means the Villager reaches world_nether without the IllegalStateException and the reproduction no longer logs the error.
