<p><code>aria-haspopup="menu"</code> is being used incorrectly on disclosure buttons. According to the spec:</p>
<blockquote><p>Authors MUST ensure that the role of the element that serves as the container for the popup content is <code>menu</code>, <code>listbox</code>, <code>tree</code>, <code>grid</code>, or <code>dialog</code>, and that the value of <code>aria-haspopup</code> matches the role of the popup container.</p>

<h3 id="summary-proposed-resolution">Proposed resolution</h3>
<p>Remove <code>aria-haspopup</code> from the disclosure buttons. <code>aria-expanded</code> already conveys that more content will be revealed.</p>
