QGraphicsView::setTransformationAnchor(AnchorUnderMouse) does not work with setInteractive(false)

Checking qgraphicsview.cpp you can notice that lastMouseMoveScenePoint, used as anchor, is not updated during mouse move events if scene Interaction is disabled.

void QGraphicsViewPrivate::mouseMoveEventHandler(QMouseEvent *event){
...
if (!sceneInteractionAllowed) return;
...
lastMouseMoveScenePoint = mouseEvent.scenePos();
...
}

In my opinion, disabling scene interaction should not affect view functionality. I think it can be easily fixed moving the assignment before the "if".
