When I'm play in creative mode on pocket edition, when i jump underneath a blue stained glass block it puts me inside the block. It is like playing on spectator mode on java edition, and being able to go inside blocks.

To recreate

Create a two block high space in creative mode with a blue stained glass block on top and then jump.
