     * form area wrapper doesn't work correctly because block module use block.tpl.php as theme wrapper for block
     * content. In this case block wrapper HTML (block wrapper and block title) will be rendered inside form area
     * wrapper, and it will be loosed after first form update with asaf. To resolve this bug we have to wrap form
     * manually on the client-side using data-asaf-area-wrapper-id attribute */
