Description:
------------
http://stackoverflow.com/questions/4029341/dom-parser-that-allows-html5-style-in-script-tag

DOM auto remove HTML closing tag in <script> tag when save. Please check test script below.


Test script:
---------------
$html = <<<HTML
<script>
    console.log('<h1>aaa</h1>');
</script>
HTML;
        $dom = new DOMDocument();
        libxml_use_internal_errors(true);
        $dom->loadHTML(mb_convert_encoding($html, 'HTML-ENTITIES', "UTF-8"), LIBXML_HTML_NODEFDTD | LIBXML_HTML_NOIMPLIED);

        echo $dom->saveHTML();
        die;

Expected result:
----------------
All content in <script> tag need to be exactly the same as original HTML code.

<script>
    console.log('<h1>aaa</h1>');
</script>

Actual result:
--------------
<script>
    console.log('<h1>aaa');
</script>

Unfortunately, libxml isn't really HTML5 compatible yet, and there
isn't much we can do about that. You have to stick to conforming
HTML 4.01, and write <\/h1>, see <https://3v4l.org/ldGmr>.

Adding LIBXML_SCHEMA_CREATE to loadHTML() as an option will fix the issue

$dom->loadHTML($html, LIBXML_SCHEMA_CREATE);
