I think I know why the bug happens, but when you reverse the default left click and right click controls, you can't open context menus in inventory, nor can you drop items.

I feel like the inventory screen treats the left click and right click as default left and right click despite changes to controls and treats it as if you both right clicked and left clicked at the same time.
