Opened shulker invalid behaviour

[Gewinum]

Issue description

Opened shulkers are somehow transparent and don't collide with players.

• Expected result: What were you expecting to happen? In vanilla, when you open shulker and stand on it, you don't fall through it.
• Actual result: What actually happened? In pocketmine server, I opened shulker while stand on it and i fall through it. Opened shulker is transparent

1. Run PMMP on 4.6.1
2. Join server
3. Stand on shulker and open it
4. Fall through it

I have no idea why this is different in vanilla vs PM. If anyone wants to investigate this, please feel free.
