Bug 75234, XHTML style element's contents appeared twice in the content model. r=peterv, sr=jst.

    nsIUnicharInputStream* uin = nsnull;

    // Create a text node holding the content

    nsCOMPtr<nsIContent> text;

    rv = NS_NewTextNode(getter_AddRefs(text));

    if (text) {

      nsCOMPtr<nsIDOMText> tc(do_QueryInterface(text));

      if (tc) {

        tc->SetData(mStyleText);

      }

      mStyleElement->AppendChildTo(text, PR_FALSE, PR_FALSE);

      text->SetDocument(mDocument, PR_FALSE, PR_TRUE);

    }

    // Create a string to hold the data and wrap it up in a unicode

    // input stream.

    rv = NS_NewStringUnicharInputStream(&uin, new nsString(mStyleText));
