    Description

      QGraphicsItem::scroll seems to do nothing when cache mode is set to ItemCoordinateCache. ItemUsesExtendedStyleOption is also enabled.

      It works if boundingRect() is passed as rect in scroll(dx, dy, rect), but according to docs boundingRect is used by default if no rect is specified.

      Attached test case (original from O. Romashin), run with -cached or export ITEMCACHE=1 to test with ItemCoordinateCache.
