Bundles can Dupe Items

If you put any number of bundles in a bundle, then fill your inventory, and afterwards place the empty bundle in a chest, pick up the bundles that are stacked together, and fill the bundle stack with an item. And then you drag the bundles so that they're all their own stacks, you can duplicate an the item that's in the bundle
i've seen bundles can only do 16, so you can get upto 16 duplicates of one item.

(I'll have images on how to reproduce it, so it'll be easier to understand me, Idk if they're going to be in order tho.)
(also, sorry if it's a dupe of another report, and if this is too many images, just wanna make sure you guys have been told about this)
