Shift-clicking X button in Creative menu can create ghost items

The bug

Sometimes, the Survival inventory in Creative is not cleared when shift-clicking onto the X button.

To reproduce

1. Load a full 9-slot quick-toolbar with X+[number]
2. Pick-block a block or item (so that one item from the quickbar gets moved to the inventory)
3. Loading that or any other quickbar with X+[number]
4. Open the Survival Inventory inside the Creative Inventory
5. Shift-click the red "Destroy Item" button
   → The items moved into the inventory out of the quickbar by pick-blocking have not been deleted
