Bug

While extending or retracting, blocks can be broken through regular and sticky pistons as well as any blocks that are being pushed or retracted.

How to reproduce

1) Place down a sticky piston facing up with a block attached to it

2) Place instantly-breakable blocks like honey blocks around the base of the piston

3) Attach the piston to a clock and, in survival, stand atop it and hold down the attack button whilst looking down into the block at an angle so that you would be breaking the honey blocks if the block below you weren't there.

4) The honey blocks will be broken through the moving block

So, what?

This bug is extremely annoying whilst using flying machine-based elevators as they become extremely delicate and easy to accidentally break
