title: How to set focus on second Accessibility element?
body: <p>I've tried to set the focus to the second element on an alert view:</p>
  <pre><code> UIAccessibilityPostNotification(UIAccessibilityScreenChangedNotification, secondElement);
  </code></pre>
  <p>It works on iOS 12 and before, but after iOS 13, the focus will initially be on the second element, but will soon be on the first.</p>
