Command /setworldspawn doesn't work in the Nether or End, but /spawnpoint does

Just to add to this, /spawnpoint doesn’t work in the End. I haven’t tested the Nether. If you do /spawnpoint in the End, you get a message saying the spawn was set in the end, but it doesn’t seem to work.

Also, using the command in the Nether and then dying and respawning in the Overworld brings a bunch of broken, floating Nether mobs over to the Overworld

Edit: This may also break the world 

This is a feature request.
