Fix crash with ScatterChartItem mouse events...
Fix crash with ScatterChartItem mouse events The ScatterChartItem should emit the clicked and hovered signal after the QGraphicsRectItem has handled the corresponding events. This is to avoid situations where the item has been changed due to the signal as it can lead to problems when handling the mouse event (like crashes due to deleted items).
