When closing the inventory while holding an item with the cursor in creative mode, the item still disappears if your inventory is full

The bug

MC-87935 still happens if your inventory is full. The item vanishes instead of being dropped like in survival mode. It also plays a hand animation from MC-220167.

How to reproduce:

1. Make sure to be in creative mode

2. Make your inventory full

3. Take any item from the creative inventory, but don’t place it anywhere

4. Close the inventory
   ❌ The item was deleted instead of being dropped.
