Duplication Glitch (NEW)

I found a duplication glitch in the bedrock version of the game partially by accident which is pretty simple, but i don't people to figure out about it. I found it myself and i have not showed anyone and nobody has made a video on it yet so it is brand new. There is a video about it linked to it

This is an explanation of how it works and how i discovered it.

When you break a block you can place it before it appears in your inventory, which it helpful and i would like for this to remain. Sometimes though, when you place it, a fake block also shows up in your inventory which vanishes easily. I discovered this while trying to change the trades of villagers. However, if the block you pick up can be broken down into smaller parts (diamond blocks for example), then you can right click on the crafting recipe in the crafting book and it attempts to make it but disappears immediately. when it disappears all you have to do is make a block update by right clicking or breaking a block, and then this makes the diamonds appear in your inventory and they are real and can be used to craft things.
