When i was flying on top of clouds on creative mode, once you got on top and went forward, you could go out of the world. And once you drop down, you land on a stone/bedrock block and it makes stone noises when you walk.

What I expected to happen was that the world limitations would stop me.

What actually happened was that once above clouds, you could walk out of the world.

Steps to Reproduce:
1. Fly above clouds.
2. Go past the world limitators.
3. Drop down.
Walla! Theres a bug!
