When an enderman is aggressive and starts teleporting randomly at day it becomes passive and still teleports randomly during night.
- Set the time to night
- Build a two block high tower and stand on it
- Spawn an enderman next to you
- Switch to survival mode and look at the enderman
- Set the time to day
- Wait until the enderman stops being aggressive
→ When you look at the enderman it will not become aggressive anymore

It looks like the problem is that the field net.minecraft.entity.ai.EntityAINearestAttackableTarget.targetEntity is not reset when net.minecraft.entity.EntityLiving.attackTarget is null. This is the case if it is day and an enderman tried to attack a player for 30 seconds. However, changing this might have unexpected side effects.
