Issues with position fixed & scrolling on iOS

The word supported needs to be taken with a pinch of salt, because there's all kinds of issues which I intend to show you in the following post. Note that I have filed bugs for a number of these during the beta of iOS 5 - but god knows how the Radar Apple thing works, so I don't know the issue numbers. MY E
