Markdown Extra footnotes don't render properly

[curtisblackwell]

On a brand new Jigsaw site using the blog starter template, I tried using Markdown Extra's footnote syntax, but the rendered markup is strange.

This points to a footnote.[^1]


[^1]: This is a footnote.

<p>
  This points to a footnote.
  <sup id="fnref:1"><a href="#fn:1" class="footnote-ref" role="doc-noteref">1</a></sup>
</p>

<div class="footnotes" role="doc-endnotes">
  <hr />
  <ol>
    <li id="fn:1" role="doc-endnote">
      <p>
        This is a footnote.
        <a href="#fnref:1" class="footnote-backref" role="doc-backlink">&#8617;</a>
      </p>
    </li>
  </ol>
</div>

What's strange is that links to footnotes are correctly rendered, but footnotes themselves seem to be stripped out.

I'm looking into why this is happening and how to fix it.

1. Would you accept a PR for this? (I've seen the contributing guidelines, just wasn't sure if this was intentional or something)
2. Do you already know where I should look to fix this problem?

False alarm. I'm using Brave Browser Nightly and there's an automatically-enabled feature called Speedreader that hid a bunch of content.
