Skeletons wearing enchanted chest plates have glowing hands

I was flying around in my world when I saw a skeleton with leather armour (it had an enchanted chestplate).

What I expected to happen:
The skeleton would have its normal bony hands

What really happened:
The skeleton had glowing hands, the same as the enchanted texture

Steps to reproduce:
1. Find a skeleton with enchanted armour
2. Look at its hands
