When firing a trident from a dispenser until it breaks, a new one will appear in your inventory, brand new.

Ok, so, if you put a trident in a dispenser, it fires it, right? Every time it does this, it wears the trident down. But, when the trident is fired enough times it breaks, instead of breaking, a new one appears in your inventory, good as new. It's a new one, as I've tested it with enchanted tridents and you get a new one without enchantments.

It's been a bug for a while now, but I have a big Drowned farm and wanted to take advantage of the bug before I reported it, y'know?
