Qt project demonstrating the problem

QGraphicsWebView silently eats hover leave events instead of passing them on to QWebPage. QWebPage also does not properly handle the Event::GraphicsSceneHoverLeave case. This means if you have something close to the edge of a page that has a hover effect (CSS or Javascript based), and you quickly mouse out of the window, it will stay hovered.

This is still the case in Qt 4.8.0-rc1, and while I have not tried against qtwebkit trunk, looking at the code it appears to still have this problem.

The attached zip file demonstrates the problem:
 * The red square, when hovered over, turns blue
 * If you very quickly mouse to the left or up out of the web view, it stays blue
 * The expect result is for the square to revert to red
