Ok, so I'm using the suggested window-scrollTo method and it's working just swimmingly everywhere except for one little sticking point.
When Safari decides to show the "Reader" button figuring I might want to save my page for later reading, it keeps the address bar up for a full 5 seconds before finally hiding it like I asked. Kind of an eternity in UX time.
Is this an iOS 6 thing or did it also do this in iOS 5? (I don't have a 5 device to test it on at the moment.) Also, is there any way to get around it?
