------- Additional Comments from Julien Chaffraix <jchaffraix at webkit.org>
This gist of this patch is to let attach() create the renderers for us so that
we can use them to generate our shadow tree later. In order for them not to be
displayed, we remove the renderer at the root of the hierarchy (which is the
<xbl> element renderer).
