Item duplication / ghost item glitch triggered by specific keyboard shortcut combination (Q + Hotbar Number Key) in Survival / Adventure mode, causing item state desynchronization and potential inventory corruption.

In Survival or Adventure mode, a specific key combination causes the game's client-side item display to desynchronize from the server-side inventory data, creating a "ghost" item.

Steps to reproduce:

1. Ensure you are in Survival or Adventure mode.

2. Have at least two different stackable items (e.g., Stone A and Dirt B) in your hotbar, each in a separate slot.

3. Select the hotbar slot containing Item A.

4. Press and hold the Q key (default "Drop Item" key), and while holding it, press the hotbar number key corresponding to the slot of Item B.

Observed Results:

• A physical, pick-up-able copy of Item A is thrown from the player.

• In the hotbar, Item A remains visually but becomes a "ghost" (disappears upon any interaction like usage, or opening/closing a container/GUI).

• The quantity of Item B is decreased by 1 as if it were consumed.

• The hotbar slot originally containing Item B may become visually empty (no icon or text) but is still functionally selectable.

Expected Results:

• Pressing Q should drop one item from the currently selected hotbar slot (Item A).

• No change should occur to Item B in its separate slot.

• Inventory state should remain consistent between client and server.

Additional Notes:

• This glitch does not create permanent duplicate items. The "ghost" item (A) is lost upon inventory refresh, leading to a net loss of one Item B and potential inventory confusion.

• The core issue appears to be an inventory state desync triggered by the specific two-key input during the item drop action.
