title: iOS iPad Fixed position breaks when keyboard is opened
body: <p>Fixed position breaks on header when I click on the "Search Form" text box field. It simply detaches from the top of the page (as it's fixed up there) and starts floating middle of the page when the virtual keyboard opens up.</p>
