Comment 3 for bug 1518002

I've attached an example application that shows the issue with the header 'sliding out'.

It should be noted that it requires the PageStack, if I just put the Page inside the MainView it appears to be fine, I assume this due to an empty header being shown, then as the page is pushed on it slides out to hide the header. It ideally needs to skip the animation when first starting, so there isn't a sliding in/out animation.
