      The bug

      If you drag an item out of a creative menu and into the Survival Inventory tab, it will crash the game.

      How to reproduce

      1. Enable Touchscreen Mode in the Controls menu
      2. Open the Creative inventory
      3. Press and hold your cursor on an item, and drag the item above the Survival Inventory icon (the chest in the bottom right)
      4. Release and quickly re-press the item (you should now see the Survival Inventory page but still be holding the item)
      5. Release the item over a slot in the Survival Inventory page
        Crash

          Palette crash was modded, but I would like to see better reproduction for dragging crash: how exactly can you drag from creative to survival menu? Are you using actual touchscreen or just mouse?

          If I just release mouse over survival icon while holding an item, it becomes ghost one (yes, it's a bug), but it doesn't crash.
