<h2>Handling PaymentResponse.prototype.onpayerdetailchange events</h2>
<p>
The test brings up the Payment Request UI window.
When shown the payment sheet, use any details and hit pay.
</p>
<p>
When asked to retry the payment:
</p>
<ol>
<li>
<p>
Change payer's name to anything.
</p>
<button onclick="runTest(this);">
Calling PaymentRequestUpdateEvent updateWith() twice throws an "InvalidStateError".
</button>
</li>
<li>
<button onclick="done();">DONE!</button>
</li>
</ol>
