Steps to reproduce the issue

A combination of #9665 and the HTML5 declarations for the core templates has caused the keepalive behavior to misbehave in the backend. Unencoding the ampersand makes it work again.

Expected result

A request to administrator/index.php?option=com_ajax&format=json with a 200 response

Actual result

A request to administrator/index.php?option=com_ajax&format=json with a 404 response

Additional comments

Checking $doc->isHtml5() isn't enough here because the core templates set this flag when they get rendered, long after the component is rendered and calls this behavior.

that i know of there is no html error in having keepalive without the & in html5 ...

For render as XHTML the problem is not the &, the problem is that for correct xhtml rendereing the scipts should be inside CDATA

Example:

This does gives error in w3c validator

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
    <meta name="viewport" content="width=device-width, initial-scale=1.0" />
    <meta http-equiv="content-type" content="text/html; charset=utf-8" />
    <title>Home</title>
    <script type="text/javascript">
        var a="/index.php?option=com_ajax&format=json";
    </script>
</head>
<body>
    <p>&nbsp;</p>

</html>
