Fixed Header sometimes setting incorrect values for the page Div's min-height and Top Padding
Header with data-position="fixed" sometimes causing incorrect values for the its div[data-role="page"] parent min-height and Top Padding. When autoInitialize is taking care of things and initializing the pages (where it just renders the first page in the html) it is drawing the content under the header. Navigating with hashes in any way(Even showing a popup menu) makes it render correct, so it appears something is missing during autoInitialize to set those properly.
