Using the Disarm Enchantment on some mobs (I am reporting this issue after an encounter with Drowned, specifically) will make the mob drop their item as intended, but not take it off their hands, allowing the player to repeatedly make the mob drop multiples of the same item over and over
I used this on a Drowned holding a Nautilus Shell and it never ran out of the item, and this also worked for Drowned holding Tridents

Oh I had two tabs of mod issues open and confused this with another one, please ignore
