When using the compacting upgrade(advanced), it will give a whole stack of blocks when it should only give one, or only a few(like a stack of coal becomes ~a stack of coal blocks)

To Reproduce**
Steps to reproduce the behavior:

1. put an advanced compacting upgrade on a backpack(I used a netherite backpack)
2. get a stack of iron ingots(works most consistently with this it seems for some reason, with coal and gold sometimes it did not compact at all, specifically after it had worked as above once)
3. I shift clicked them in, upon initial discovery, not testing, it seemed to also work on coal collected via magnet
4. That's it, should give you way more blocks than would be expected

Expected behavior
A number of blocks and remaining items equivalent to the amount placed into backpack
