Description

When loading a XHTML document with JavaScript into html5-php I expect the <script>//<![CDATA[ conversion to behave like it does in plain old \DOMDocument. Instead they get turned into htmlentities, breaking the JavaScript on our target platforms (ebook readers).

Expected:

<script>
//<![CDATA[
for ( var i = 0; i < 10; i++ ) {
	console.log(i);
}
//]]>
</script>

Actual:

<script>
//&lt;![CDATA[
for ( var i = 0; i &lt; 10; i++ ) {
	console.log(i);
}
//]]&gt;
</script>

< becomes &lt;, > becomes &gt;, ...

Test case:

$body = '<?xml version="1.0" encoding="UTF-8" ?>
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en">
<head>
<title>Test</title>
</head>
<body>
<p>Hi There!</p>
<script>
//<![CDATA[
for ( var i = 0; i < 10; i++ ) {
	console.log(i);
}
//]]>
</script>
</body>
</html>';

$d1 = new \DOMDocument();
$d1->loadXml( $body );
echo $d1->saveXML();

$mm = new \Masterminds\HTML5();
$d2 = $mm->loadHTML( $body );
echo $d2->saveXML();

Research direction

Start by running the supplied PHP test case and compare DOMDocument with Masterminds\HTML5 loadHTML followed by saveXML. Trace the parser and serializer path responsible for script content; done means CDATA markers and comparison operators remain literal instead of becoming HTML entities.
