Putting an infinte bucket in an anvil

There is a restriction on putting an infinite bucket in an anvil, but you can bypass it by using F (place item in offhand, hover over anvil slot, press F). It does not let you actually re-name the item however. You can also lose XP from this - if you change the item name, it appears for a split second. If you remove it in the split second it takes your XP but does not give you an item. (I think it's safe to say this won't happen on accident lol). related note, you can re-name an infinite bucket with /itemname (rank perk) and it does not affect functionality, though using the bucket once clears the name. (this is my guess as to why it's disabled in the anvil)
