The rows in this "LiveGrid demo" don't look correct, they don't appear to have been transformed or had style applied. Result differs from Firefox.

The problem here is that the result of the transformation is plain XML, without an XHTML namespace. So, tags have no meaning when the result is inserted into the HTML document with appendChild(). I don't know why Firefox styles it, maybe they have some good reason?
To work around this, add an XSLT output directive: "<xsl:output method="html"/>".
I think I know the reason - Firefox defaults the output method to HTML because the target document of transformToFragment() is an HTML one.
