The gateway is expected the end gateway to teleport entities to the end cities.
But the portal instead teleported them back to the obsidian platform where they started.

Steps to Reproduce:
1.Go to the end dimension.
2.Kill the dragon
3.Throw an ender pearl into the gateway. (THE GATEWAY SHOULD TELEPORT THE PLAYER TO THE END CITIES, BUT THE GLITCH BRINGS THE PLAYER BACK TO THE OBSIDIAN PLATFORM WHERE THEY STARTED.)
