Moving items around in `InventoryGridEx` sometimes messes up all the item positions

[peter-kish]

One thing that I've noticed though... Sometimes (really not always) if I swap items, example I put the item from position 6 to position 2 the item on position 4 gets placed on other position. I'll try to replicate how I trigger this on the weekend.

So far, I can only assume that it has something to do with the _sort_if_needed() method inside InventoryGrid.
