Right-clicking on a stack of items dragged outside of the "Survival Inventory" tab of the creative inventory drops the full amount

Steps to reproduce:

1. Enter creative mode

2. Open inventory

3. Grab a full stack of any item/block of your choosing

4. Go to the “Survival Inventory” tab

5. Drag the stack outside of your inventory and right click

Expected result:

Like when in every other tab in the creative inventory (and even the inventory of survival mode itself), only a single block/item will be dropped from the stack.

Actual result:

The full stack is dropped.
