/clear does not properly affect the item on the mouse pointer after crafting it

If you attempt to clear an item directly after crafting it, it will become a ghost item that drops upon closing the GUI.

 

To recreate the bug

 

Add a recipe

Add an advancement to detect when the recipe is unlocked. Give that advancement a rewarding function that clears the crafted item.

 

Close the GUI.
