Ditto.

         return renderer->style();
     // <option> and <optgroup> can be styled even if they don't get renderers,
     // so they store their style internally and return it through nonRendererStyle().
     // We check here explicitly to avoid the virtual call in the common case.
     if (isHTMLOptGroupElement(*this) || isHTMLOptionElement(this))
         return nonRendererStyle();
     return 0;
 }
