Affects Version/s: Minecraft 17w50a
Fix Version/s: None
Steps to reproduce:
1. Place a chest/trapped chest.
2. Notice that it opens normally.
3. Place a Glowstone block above it.
4. Notice that it can no longer open.
Side note 1: You still can open chests under slabs and stairs and other transparent blocks.
Side note 2: Glowstone still acts like a transparent block in redstone (i.e. cannot be strongly powered)
