Looking for patch that fix item loss when dying before using said item

Hello, there is a patch somewhere that fix the item loss bug when you select an item but die (or battle ends) before using it or use an item with Throw but die before using it (which result in the item being loss). 

Does anyone know where to find it? I've searched pretty much everywhere. The patch is supposed to make it so the item is only consumed when the command happen so if you die or if battle ends between selecting the item and using it, there is no item loss. this patch is pretty important and that would be great if someone know where to find it.

Thanks!
