Prevent QWebPage::setView() from changing the viewport size on the fly in case the view doesn't actually change. QWebPage::setView() is called upon every QWebGraphicsItem::hoverMoveEvent(), which forces the viewport size to be equal to the size of the whole graphics view. The geometry of a single graphics item rarely matches the geometry of the whole graphics view.
