Hidden sibling elements are not chunker-sections

<p>Before sections</p>

<h2>Lorem ipsum dolor sit amet</h2>

<p>Consectetur adipiscing elit. Phasellus tincidunt luctus mi non sodales. Aliquam blandit, est eget euismod rutrum, purus ante cursus turpis, eu faucibus lacus augue id nisl. Mauris pellentesque ac felis in sodales. Curabitur placerat sagittis lacus.</p>

Is rendering before the change like this:

<p style="display: none;">Before sections</p>
<div class="chunker-section"><h2 id="lorem-ipsum-dolor-sit-amet">Lorem ipsum dolor sit amet<a href="#lorem-ipsum-dolor-sit-amet" class="anchor">#</a></h2>
<button class="action--print-section">Print this section</button>
<span class="print-section-line"></span>

<p>Consectetur adipiscing elit. Phasellus tincidunt luctus mi non sodales. Aliquam blandit, est eget euismod rutrum, purus ante cursus turpis, eu faucibus lacus augue id nisl. Mauris pellentesque ac felis in sodales. Curabitur placerat sagittis lacus.</p>

</div>

After applying the patch:

<p>Before sections</p>
<div class="chunker-section"><h2 id="lorem-ipsum-dolor-sit-amet">Lorem ipsum dolor sit amet<a href="#lorem-ipsum-dolor-sit-amet" class="anchor">#</a></h2>
<button class="action--print-section">Print this section</button>
<span class="print-section-line"></span>

<p>Consectetur adipiscing elit. Phasellus tincidunt luctus mi non sodales. Aliquam blandit, est eget euismod rutrum, purus ante cursus turpis, eu faucibus lacus augue id nisl. Mauris pellentesque ac felis in sodales. Curabitur placerat sagittis lacus.</p>

</div>

The content before the first section is correctly displayed and remains visible as you page through the chunked content.
