hook for CKeditor 4.25.1

[MikePitta]

Hi.

This hook to ckeditor versione 4.22 works

<?php
add_hook('AdminAreaHeadOutput', 1, function($vars) {
    return '<script src="https://cdn.ckeditor.com/4.22.0/standard/ckeditor.js"></script>
            <script>window.onload = function() { CKEDITOR.replace("replymessage"); };</script>';
});
?>

but with a warning about vulnerabilities.

This instead, as well as for any newer ckeditor version, doesn't work.

<?php
add_hook('AdminAreaHeadOutput', 1, function($vars) {
    return '<script src="https://cdn.ckeditor.com/4.25.1-lts/standard/ckeditor.js"></script>
            <script>window.onload = function() { CKEDITOR.replace("replymessage"); };</script>';
});
?>

Any way to make it work?
