Enderman becomes passive when sunlight comes

when the time is night if I stared at enderman it will start attacking me but when the light level becomes more than 7 (when sun rises) enderman become passive and does not attack me even if I hit it or stare at it.

How to make it happens:

1-set time to night
2-spawn an enderman
3-attack the enderman
4-set time to day
5-wait some seconds
6-the enderman will become passive and will not care if you attack it
