  <p>
The dialog below is incorrectly positioned within a stacking context.
It should generate a console warning message, and place the <code>_dialog_overlay</code> in a different place in order to try to work around the problem without moving the dialog itself.
  </p>

<div style="position: absolute; top: 100px; left: 10vw; width: 80vw; height: 400px; background: blue; opacity: 0.7;">

<dialog>
  <form method="dialog">
    <input type="submit" />
  </form>
  <p>
    Help, I'm inside an extra stacking context D:

</dialog>

</div>

<button id="show">Show Dialog</button>

var dialog = document.querySelector('dialog');
dialogPolyfill.registerDialog(dialog);
dialog.showModal();

show.addEventListener('click', function() {
  dialog.showModal();
});
