Inventory w/category filter scrolls to top when item dialog is closed

[zultron]

In the inventory, when "all" categories are selected, clicking an item and then closing the dialog leaves the inventory list scroll position unchanged. Good!

But when any category is selected, closing the dialog causes the inventory list to scroll back up to the top. This is frustrating when browsing a category item-by-item, for example when checking out the new awesome weapon damage modifiers!
