QGraphicsView + AnchorUnderMouse + setContextMenu (zoom issue)

[Drus]

As example - elasticnodes

code adds a menu
@
node6->setPos(50, 0);
node7->setPos(-50, 50);
node8->setPos(0, 50);
node9->setPos(50, 50);

addAction(new QAction(QObject::tr("Anchor"),this));
addAction(new QAction(QObject::tr("Under"),this));
addAction(new QAction(QObject::tr("Mouse"),this));
addAction(new QAction(QObject::tr("Not"),this));
addAction(new QAction(QObject::tr("Work"),this));
addAction(new QAction(QObject::tr("Click"),this));
addAction(new QAction(QObject::tr("To"),this));
addAction(new QAction(QObject::tr("Repair"),this));
setContextMenuPolicy(Qt::ActionsContextMenu);

}@

If you click outside of the menu - does not work AnchorUnderMouse.
If you click a menu item - and it works well
