Getting framebuster code on consent page while doing google oauth

[sjnonweb]

I'm trying to do google Oauth and i can submit Email and Password forms but when the browser navigates to consent page i get framebuster code and the browser is not able to get around that. This is what i get on body:

<noscript>
  <meta http-equiv="refresh" content="0;url=/o/noscript">
</noscript>
<!-- framebuster code starts here -->
<style nonce="mblvj0tjsrS61nO4S0oBmILXhsY">
  plaintext {
    display: none
  }
</style>
<script nonce="mblvj0tjsrS61nO4S0oBmILXhsY">
  (function () {
    try {
      var win = this;
      while ("<plaintext>") {
        if (win.parent == win)
          break;
        eval("win.frameElement.src").substr(0, 1);
        win = win.parent;
      }
      if (win.frameElement != null) throw 'busted';
      document.write("\x3Cxmp style\x3Ddisplay:none\x3E");
    } catch (e) {
      try {
        if (!open(location, '_top'))
          alert('this content cant be framed');
        top.location = location;
      } catch (e) { }
    }
  })();
</script>
<!-- do not remove the plaintext nor xmp tags -->
<plaintext>
  <xmp>.</xmp>
  <!-- framebuster code ends here -->

As you can see its not valid html with all the opening and closing tags so the browser is not able to parse form#connect-approve. Has someone else faced this problem? Is javascript not supported in this browser.
