Dipping Poison does work, but I just realised how awkward it is to use. You need to have the bow with the enchantment in your main hand and the potion in your offhand and drink the potion, which means that there needs to be no arrows in your inventory, otherwise the bow will try to fire rather than the player trying to drink the potion.

Changed Dipping Poison to function by holding bow in offhand and drinking potion with main hand to allow for it to work with arrows in inventory (4b977d2)
