Pushed Slimeblocks Bug/Fall damage on air

If you crouch to the very edge of a Slime Block to where you can't go anymore, then push the Slime Block up with a piston, when you land you will take fall damage. Also you will not bounce back up. This happens because shifting to the edge of a block puts you in the state of being on the other block, but that block is air, therefore taking fall damage on air is a bug.
