Summary

Let's say there's a craft recipe of this shape:

.=empty
X=item

.X.
X.X
.X.

But you're current craft grid look like this:

XXX
X.X
XXX

What I used to do in such a situation is to move my mouse to one of the corner slots and click to pickup a stack, and then move to the other corners and doubleclick at each to add the slot to the stack.
But this doesn't work anymore. Since #13146, the doubleclick instead picks up all the items. I find this pretty annoying.

(Not sure if this is bug enough for bug label. Feel free to remove.)

Possible solution: Only do the collect all thing if the second click in the doubleclick caused a drop, not a pickup.

Steps to reproduce

• Put multiple stackable to each other items in your craftgrid, in different slots.
• Grab one item.
• Go to another slot.
• Doubleclick, to stack with the other slot and pick it up again.
• Expected / old behaviour: The new slot is added to your selected stack.
  (Or more correct: The previously selected slot is stacked to the new slot, and the new slot is now selected.)
• Actual behaviour: All stackable slots from the grid are collected to your hand.
