Top face of portal is invisible

It's not completely invisible, only the top face is being culled.

Okay. Still, it is a glitch, and people are taking advantage of it on my friend's server.

How can one take advantage of it since that block is unobtainable for normal players without cheats ?

I mean the admins. They are quite pranksters. I am coming up with a command block system to detect admins that do prank with this block but in the meantime, a cliff may be the next trip to the nether!

In 14w18a, this affects all sides. Maybe Intended

This is kind of unrelated, but I am posting it anyway...
I decided to visit the MCPE side of JIRA and noticed how few modrators acctually visit MCPE bug reporting.

I think this should be closed.

@~[HB_ian]: Why ? This is still in 14w21b.

No longer obtainable using /give command. Should be closed.
