RegEx error in cookiebot_addons_manipulate_script

The RegEx within addons/lib/helper.php seems to encounter an error when parsing scripts echo’ed via wp_head action.

I’ve called preg_last_error() when $updated_scripts returns NULL, which returns PREG_JIT_STACKLIMIT_ERROR. I’ve sprinkled the function with some debug logging, which I’m happy to share:

Cookiebot version: 2.0.3
Wordpress: 4.9.8
PHP 7.2.9

P.S. For now, I’ve applied somewhat of a bandaid at the end of the function:

if ($updated_scripts === null) {
    $updated_scripts = $buffer;
}

return $updated_scripts;
