EPUB metadata: When rendering the first page as cover, render it as XHTML. This means that if the EPUB is not valid XHTML the cover wont be rendered correctly. Necessary for rendering of SVG elements in the page when it does not have an .xhtml extension. Fixes #7909 (Issue with HarperCollins EPUB Covers)
