Duplicate Item Machine

A stack of 64 or a shulker chest can be duplicated by a simple machine consisting of 9 redstone repeaters, 2 redstone, a sticky piston, and a button. There are other versions of this machine that can be found on youtube but I have only tried the version I mentioned above. A simple search for "Bedrock item duplication glitch" will provide adequate video examples.

This is a game breaking bug which completely undermines survival. I searched for this bug before posting this and found it had been reported, however it must have been posted in the wrong section because the report was redirected to the Bedrock bug reporting page and marked as resolved.
