Clicking any item inside gui with off-hand causes duplication!

[HW2955]

(Tested with this environment)
Paper-341 (1.18.2)
Java 17.0.3.1

• cirrus-spigot-example-2.0.0
• EssentialxxX-2.19.4
• FAWE-Bukkit-2.3.1
• Skript 2.6.3
• Vault

Actions to replicate:

1. Use the /test command from example usage plugin,
2. Click the 'F' key (switch to off-hand) while cursor is on any item,
   2.1. This produces an error (error.txt)
3. Close the menu,
4. (Note: while player is in survival mode, this only produces a ghost item, though creative mode creates it.)
   Open your inventory (probably works with opening other inventories aswell)
5. Get duplicated item in your off-hand slot.

Hopefully someone smart enough finds a good fix for this, I've fixed this bug in my framework by adding NBT tag to all gui-items and removing them wherever player causes InventoryClickEvent, though i don't find it really optimal solution.

I really love this framework and would love to see it being expanded upon, and documentation being published.
