Inventory close with mouse key fix

Fix mouse key item drop

Should be compatible with any MC versions just re-uploaded (some kind of glitch)

Forge doesn't support multi-version compatible mods. sad Forge. I used mixins for this (This was far the best option) I also lost this version's source code. I may recreate it later :D

It should support any fabric versions.

(this is why no MC version is set for this file)

Fabric API not required.
