Also a good way to reproduce is with endermans, build a platform in the end and overworld at the same coordinates. Get one player to stay in the end (to load / tick the world / chunks).
Now teleport to the end platform and look at an enderman to make him attack you. Now teleport to the overworld platform and observe how you still get damage from the enderman from the end.
