Using External Panels, as in example -> http://demos.jquerymobile.com/1.4.4/panel-external-internal/
They don't render correctly, if you open the left panel you will notice a thick black band across the bottom of the page, and if you open the right panel you don't get the black band but it does not render to the bottom of the page.
Also I've noticed if you click the body of the page, the footer jumps up and down..
Looking at the size of the black bar, it appears to be twice the size of the header. Using chrome inspector to me it looks like the calculation for min-height is doubling up.
Having this working would be great, as page transitions with a fixed header look really nice.. Eg. The content can be made to slide in & out, and the headers stay fixed.
Tested in latest Chrome / Firefox and IE9, all do the same.
