Chest lighting glitch

A chest placed underneath another chest turns black due to a lighting glitch

What I expected to happen was...:
Chest appears at regular lighting level

What actually happened was...:
The bottom chests turned black due to lighting glitch

Steps to Reproduce:
1. Place any block on top of each other(2 high pillar)
2. Place a chest in front of the two high pillar
3. Place a chest on top of the other chest
4. Bottom chest turns black
5. (Two high pillar used to place chests -it isn't necessary to reproduce the bug)
