Create a new world with the attached data pack installed. Run the following commands to give the player the included recipes:

/recipe give @s minecraft:working
/recipe give @s minecraft:broken

The JSON files for these two recipes are identical except for that `minecraft:working` transmutes an iron pickaxe into a golden pickaxe and `minecraft:broken` transmutes a diamond pickaxe into another diamond pickaxe.

The `minecraft:working` recipe works entirely as expected, but the `minecraft:broken` recipe does not yield any result. Even though the recipe shows up in the crafting book, and you can click it to move the crafting ingredients into the crafting table, the recipe yields nothing.
