Endermen are provoked by players under the invisibility effect

When invisible, endermen can see you when you stare at them and in the end they attack you
If a player with the invisibility effect is wearing armor, he should be noticed by an enderman (as well as other mobs).
MC-89309:

It is intentional that mobs can sometimes see invisible players up to a distance of 3.5 metres (or even further if the player is wearing armor).

It is intentional that mobs (except slimes) who are attacked by invisible players can see their attacker and fight back.

Steps to Reproduce:

1. Drink a potion of invisibility
2. Spawn an enderman
3. Switch to Survival mode
4. Stare at the enderman

Observed Results:
The enderman is provoked and starts attacking the player.

Expected Results:
The enderman should remain neutral when staring at it.
