Only able to remove topmost item from bundle with right-click.

When attempting to remove an item from within a bundle, player may right-click to remove topmost item. Also, when attempting to remove an item that is not the topmost item, player may use scroll-wheel to select another item, and right-click to remove selected item.

This bug affects the ability to select any item that is not the topmost item in the bundle. Player used scroll-wheel to select item that is not topmost item in the bundle and then used right-click, but only topmost item was removed from the bundle.
