I am using resizeToContents and as far as I can tell by the code the only
thing it does is resize the GraphicsWebView to match the mainframe size.
The issue here is that using window.scrollTo will affect the rendering of
the page on the graphicsview. I tried on Grob and it works but if you try
on a qml WebView it will move the page "out"  of the view.

Please try this URL on a QML WebView on Harmattan (I can provide an example
app later - don't have one ready):
