So today I was messing around with the new crossbow and discovered that if you hit an enderman with a spectral arrow it will give the enderman glowing while not damaging it.This lead me to test other arrows on them with the same general affect as for example poison gave the enderman poison and you can get where this is going.
Nothing big but a bug none the less.
Thank you for your report!
