Affects Version/s: Minecraft 15w42a, Minecraft 15w43a
Fix Version/s: None
when placing a tile entity at y=255, clicking on the tile entity to bring up the GUI doesn't work when clicking from the face of the block facing y=256. Command blocks do show a GUI but it's all blacked out.
How to reproduce:
1. create a new world
2. run the following commands:
# it doesn't have to be a command block but it's easiest to see the bug
3. right click. The GUI will not work properly.
