	 * XHTML extracts the contents of the SCRIPT element and then the XML parser
	 * decodes character references and other syntax elements. This can lead to
	 * misinterpretation of the script contents or invalid XHTML documents.
	 *
	 * Wrapping the contents in a CDATA section instructs the XML parser not to
	 * transform the contents of the SCRIPT element before passing them to the
	 * JavaScript engine.
	 *
	 * Example:
	 *
	 *     <script>console.log('&hellip;');</script>
	 *
	 *     In an HTML document this would print "&hellip;" to the console,
	 *     but in an XHTML document it would print "…" to the console.
	 *
	 *     <script>console.log('An image is <img> in HTML');</script>
	 *
	 *     In an HTML document this would print "An image is <img> in HTML",
	 *     but it's an invalid XHTML document because it interprets the `<img>`
	 *     as an empty tag missing its closing `/`.
	 *
	 * @see https://www.w3.org/TR/xhtml1/#h-4.8
