Teleporting non-player entities to a different dimension despawns them

Steps to reproduce

1. Have Player 1 be in the overworld and Player 2 be in the nether
2. Player 2 summons a villager.
3. Player 1 runs either of the following commands:
   /tp @e[type = villager] @s
   /execute @e[type = villager] ~~~ tp <Player 1>

Expected result

The villager teleports to Player 1.

Actual result

The command feedback says that the villager teleports to Player 1, but the villager actually despawns.
