what’s happening(setup) : When a Piston is constantly powered by a red stone clock, and is pulling/pushing a block.
What’s supposed to happen when breaking the block from above: the block breaks like usual. The piston isn’t affected
What’s actually happening: The piston breaks leaving the block floating in the air

This is likely only possible in creative mode because of instant mining. Moving blocks only exist for 2 ticks, and pistons take some time to mine in survival.
The fact that moving blocks exist for 2 ticks instead of just 1 tick is what MCPE-103544 is about.
