the footnote extra expects to only parse one document over the Markup's lifetime, and writes the footnotes to the bottom of every page that is rendered (again assuming only one) with links back to the reference having one parser for the entire app, naturally, introduced ever-increasing footnote links and every footnote on the site showing up on every page. this was not intended in some light testing, doing this per-request has a nominal effect on performance
