Major Duplication Exploit

There has been a major duplication exploit in Minecraft Bedrock Edition that has been going on since version 1.11. The duplication exploit involves putting an item, any item (shulker, diamonds, beacons, etc.) into a container block (chest, barrel, hopper, dropper, etc) that is placed right next to a sticky piston. You'd then activate the piston using a button and that will push the container forward, then at the exact moment the piston retracts and pulls the container back, you'd take the item out, This will create a duplicate of the item as seen in this video.

Anyways I hope this gets fixed in the next update!
