aria-live="polite" doesn't announce selected form controls like radio button/checkbox
<p>Facing a strange problem with <code>aria-live="polite"</code>, if the loaded content has form controls, like radio buttons or checkbox.</p>

<p>NVDA just reads the text of radio buttons, but doesn't announce anything about which one is selected or checked.</p>

<pre><code>&lt;a aria-label="Click Me" href="#"&gt;Click Me&lt;/a&gt;
&lt;div id="myForm" aria-live="polite"&gt;&lt;/div&gt;
</code></pre>
