{{ page.content | safe }}

build command: zola build

Expected Behavior

<h1>header<sup class="footnote-reference"><a href="#1">1</a></sup></h1>
<p>another<sup class="footnote-reference"><a href="#2">2</a></sup> footnote.</p>
<div class="footnote-definition" id="1"><sup class="footnote-definition-label">1</sup>
<p>footnote one
<sup class="footnote-reference"><a href="#2">2</a></sup>: footnote two</p>
</div>

Current Behavior

<sup class="footnote-reference"><a href="#1">1</a></sup><h1 id="header">header</h1>
<p>another<sup class="footnote-reference"><a href="#2">2</a></sup> footnote.</p>
<div class="footnote-definition" id="1"><sup class="footnote-definition-label">1</sup>
<p>footnote one
<sup class="footnote-reference"><a href="#2">2</a></sup>: footnote two</p>
</div>
