Issue was only with absolute positioned elements, so I modified jQuery function (// lines).

    function getWidthOrHeight(elem, name, extra) {

        //deletes position//
        var $elem = $(elem); //
        var position = $elem.css('position'); //
        $elem.css('position', ''); //

        // Start with offset property
        var val = name === "width" ? elem.offsetWidth : elem.offsetHeight,
        i = name === "width" ? 1 : 0,
        len = 4;

        if (val > 0) {
            if (extra !== "border") {
                for (; i < len; i += 2) {
                    if (!extra) {
                        val -= parseFloat(jQuery.css(elem, "padding" + cssExpand[i])) || 0;
                    }
                    if (extra === "margin") {
                        val += parseFloat(jQuery.css(elem, extra + cssExpand[i])) || 0;
                    } else {
                        val -= parseFloat(jQuery.css(elem, "border" + cssExpand[i] + "Width")) || 0;
                    }
                }
            }

            //sets position//
            $elem.css('position', position); //

            return val + "px";
        }
