Endermen teleporting into players in NM dungeon

Theres been an bug report about this but it was closed without any more information why, so I am making a new one since it basically became way way harder to do NM dungeon alone, since the endermen keep teleporting inside of everyone. I heard somewhere that its intentional to make it harder for people to just get carried through it but there are way better ways to fix that (I would have a good idea if interested)
