Please confirm this isn't a support request.
Yes
The problem is in public function html(): string { return trim(substr($this->document->saveHTML(), 23)); }
the const of 23 is wrong for the use case since libxml2 changed the output and added it as a comment. Better use regx to remove xml encoding element.
