[Bug] Crash MC 1.21.1 client when MC-577 is ON

[Aesthir]

Bug Description

Client crashes whenever mass drop straight from crafting result slot is attempted but mouse is clicked next to the item (or somewhere else entirely). Turning off MC-577 fixes the crash, but no longer supports using mouse to drop items from crafting slot. Lose/lose. :^/

How to Reproduce?

1. Turn on MC-577.
2. Go to crafting grid (or elsewhere, crash happens in many places).
3. Try to use mouse button to mass drop items straight from the crafting result slot (works), but miss the slot (click anywhere other than the slot item).
4. Client crashes.

Expected Behavior

1. Turn on MC-577
2. Open crafting grid with no room in inventory for crafted items.
3. Craft all items, throwing them instead of placing them in (full) inventory.
4. Client doesn't crash. Items on the ground.
