  Click on each button in sequence from top to bottom without refreshing the page.
  Each button will bring up the Payment Request UI window.
</p>
<p>
  When the payment sheet is shown, select a different shipping address.
  If you have to manually abort the test from the payment sheet, then the
  test has failed.

<ol>
  <li>
    <button onclick="testFireEvents(this)">
      If there are duplicate shippingOption ids, then abort payment request.
