Item statistics incorrectly add the halved stack amount on right click of a crafted item

Right-clicking a created item stack in the crafting table will extract the entire stack, but the "Item statistics" will incorrectly add the halved amount to the statistics. This is probably an artifact of the default stack behavior on right-click.

In the example I craft 4 sticks from 2 wooden planks. I right click this stack, which takes the entire stack on my cursor. The "Item Statistics" will now show I crafted 2 sticks, or half the amount, which is impossible.
