In the PC version of minecraft there is a piston principal where if a sticky piston receives a one tick delay the block will rise up but will stay there and the piston will proceed to fall back down; if another one tick pulse is given the piston will lift up, grab the 'floating' block and then fall down with the block. However, this principal is missing in MCPE 0.15.0 if a 1 tick pulse is given to a piston it will lift the block as well as take it back down. This is an issue and things like: Double Block Extenders Cannot Exist In MCPE As It Relies on this 1 tick principle to function. So please implement this principle into MCPE

Thank You
