IntersectsItemBoundingRect mode doesn't work on QGraphicsRectItem with custom shape

When calling QGrahpicsScene::items() with IntersectsItemBoundingRect, items with custom shapes are not selected if the point is outside of the shape. Consider the following code:

class ZeroShapeItem : public QGraphicsRectItem {
public:
	ZeroShapeItem(QRectF r) : QGraphicsRectItem(r) {}
	QPainterPath shape() const { return QPainterPath(); }
};

main()
{
    QGraphicsScene scene;
    scene.addItem(new ZeroShapeItem(QRectF(0, 0, 100, 100)));    
    QList<QGraphicsItem*> items = scene.items(QPointF(10, 10), Qt::IntersectsItemBoundingRect, Qt::AscendingOrder);
}

The returned items will be empty since the scene still calls contains() after testing for bounding rects intersection (at around line 160 in qgraphicssceneindex.cpp). By default. contains() test for shape intersection. Since the item has an empty shape, it's excluded.

From the wording of the doucmentation, IntersectsItemBoundingRect should return items whose bounds intersects the requested point regardless of its shape.
