<h1>Cross-origin start URLs are invalid</h1>

<script>

  // Force the port of the origin to be ports[https][0] (likely :8443)

  // we treat the start_url's port ports[https][1] (likely :8444) to be another origin that we fail against

  if (window.location.origin !== "https://{{host}}:{{ports[https][0]}}") {

    window.location = new URL(window.location.pathname, "https://{{host}}:{{ports[https][0]}}")

</script>

<p>

  To pass, the start URL must not be fail.html because it's not same origin.
