Duplicate chest contents by forcing game to exit

this is a dup in minecraft. I found it by accident

I don't want the game to have such errors. here's how to make it

 

it is necessary to put a chest and put the necessary object in it, dig 4 blocks next to it and pick it up. abruptly exit the game and go back. two blocks will be raised and the item will be in the inventory and in the chest. tobish the item will be twice as large. I can't show it at the moment, but you can check it yourself on the phone version of the game

 

many thanks to the online translator
