safari - iOS iPad Fixed position breaks when keyboard is opened

Question

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.

Normal:

I really like this solution (http://dansajin.com/2012/12/07/fix-position-fixed/). I packaged it up into a little jQuery plugin so I could:

• Set which parent gets the class
• Set which elements this applies to (don't forget "textarea" and "select").
• Set what the parent class name is
• Allow it to be chained
• Allow it to be used multiple times

Code example:

$.fn.mobileFix = function (options) {
    var $parent = $(this),

    $(document)
    .on('focus', options.inputElements, function(e) {
        $parent.addClass(options.addClass);
    })
    .on('blur', options.inputElements, function(e) {
        $parent.removeClass(options.addClass);

        // Fix for some scenarios where you need to start scrolling
        setTimeout(function() {
            $(document).scrollTop($(document).scrollTop())
        }, 1);
    });

    return this; // Allowing chaining
};

// Only on touch devices
if (Modernizr.touch) {
    $("body").mobileFix({ // Pass parent to apply to
        inputElements: "input,textarea,select", // Pass activation child elements
        addClass: "fixfixed" // Pass class name
    });
}

EDIT: Removed unnecessary element
