QGraphicsView: unifiedWindowAndTitleBar displays the wrong cursor shape in specific areas - Mac OS X

When calling setUnifiedWindowAndTitleBar() on a mainwindow containing a graphicsview, then a small area below the action area in the toolbar/menubar will display the same cursor as when hovering over the toolbar, instead of the cursor belonging to the graphicsview.
It appears as the actions' bounding rect is masking part of the graphicsview.
