[data] Use correct syntax to unset CSS attributes (closes #8602446) 'default' is actually a recognized CSS cursor name (the regular pointer). Using this value doesn't revert to whatever cursor DOM elements have by default ('pointer' on links, 'text' on text, etc). The proper way to unset a CSS attribute on DOM elements is to set it to an empty string. http://stackoverflow.com/questions/2027935/how-to-remove-css-property-using-javascript

jQuery.fn.autoResize = function() {
    // remove enforced with / height (by CSS and/or HTML attributes)
    this.css("width", "auto").css("height", "auto");
    this.removeAttr("width").removeAttr("height"); // Remove
    // compute image size / max allowed size to fit screen
    var imgHSize = this.width();
    var maxHSize = $(window).width() - ($(document).width() - imgHSize);
    var imgVSize = this.height();
    // we don't mind if content in [content]footer moved out of the screen
    var maxVSize = $(window).height() - ($(document).height() - imgVSize) + $('#footer').height() + $('#contentfooter').height();
    if (maxHSize > 0 && maxVSize > 0) {
        // if image don't fit screen, set width or height so that
        // browser keep img ratio, ensuring the other dimension will
        // also fit the screen
        if (imgHSize > maxHSize && ((imgVSize / imgHSize) * maxHSize) <= maxVSize) {
            this.css("width", maxHSize);
        } else if (imgVSize > maxVSize && ((imgHSize / imgVSize) * maxVSize) <= maxHSize) {
            this.css("height", maxVSize);
        }
        else {
            // image already fit in screen, don't scale it up
        }
