If I include a Markdown with multiple levels of headers (e.g. `#`, `##`...), the headers do not appear in MediaWiki's automatically generated table of contents (only those headers defined outside the `<markdown>` tags appear).
Is it possible to also include headers inside the Markdown using this extension? There's the `toc` option in Parsdown Extended but that generates a TOC inline at the top of the page which is separate from the regular MediaWiki table of contents.
