potiential exploit for duplication

item kinda just turned jankey. i expected it just to drop one of the items i was holding but instead it dropped the item i went to, but it looked like the item i came from

Steps to Reproduce:
1. have two items in your inventory,
2. have item #1 in your hand
3. switch to item #2 and drop the item very quickly/at the same time, requires a specific frame
