Function mem6::htmltemplatemod::get_root_element

pub fn get_root_element<'a>(
    rrc: &RootRenderingComponent, 
    bump: &'a Bump, 
    html_template: &str, 
    html_or_svg_parent: HtmlOrSvg
) -> Result<Node<'a>, String>

get root element Node.
I wanted to use dodrio::Node, but it has only private methods.
I must use dodrio element_builder.
