Describe the bug
1.16.5 / 1.19.2
Player obtaining backpacks without ever holding them can be stored inside inception backpack and stacked on top of eachother with stack upgrade

Afterwards any thing thats magnetted into backpack from magnet upgrade will be put in both.
The backpacks will gain eachothers contents even when seperated as long as the player did not hold them.

Both bags have same uuid as well

To Reproduce

Steps to reproduce the behavior:

1.16.5

1. create backpack give it inception upgrade, stack upgrade and magnet
2. create 2 more backpacks without ever holding them in your hand
3. insert them inside inception backpack and they will stack
4. gather a bunch of items without ever holding backpacks and they will duplicate contents

1.19.2

1. create backpack give it inception upgrade, stack upgrade and magnet
2. craft 2 more backpacks but indivually never making the base backpack by inserting more than 1 item into the crafting grid
   3.Insert them inside inception backpack and they will stack
3. gather a bunch of items without ever holding backpacks and they will duplicate contents

Expected behavior
Backpacks do not stack while using inception upgrade even with stack upgrade
