        /*This function is specifically designed to check the parent elements for the noSwiping class, up to the wrapper.
        We need to check parents because while onTouchStart bubbles, _this.isTouched is checked in onTouchStart, which stops the bubbling.
        So, if a text box, for example, is the initial target, and the parent slide container has the noSwiping class, the _this.isTouched
        check will never find it, and what was supposed to be noSwiping is able to be swiped.
        This function will iterate up and check for the noSwiping class in parents, up through the wrapperClass.*/
