The new snapshot 19w39a has a new bug in the lighting texture of mobs.

Mobs are with a dark texture when the player is a bit far away even in daylight.
What I expected to happen was...:
Mobs with normal texture.

What actually happened was...:
Mobs are with a dark texture when the player is a bit far away even in daylight.

Steps to Reproduce:
1. Get a little far away from the mob.
2. Just look at him.
