Can you check assert_equals(e.ports.length, 0); here?

[jungkees, 2016/11/14 14:17:11]

Done.

           assert_equals(message, 'Sending message via clients');
           return new Promise(resolve => {
               w.navigator.serviceWorker.onmessage = resolve;
             });
         })
       .then(e => { assert_equals(e.data, 'quit'); });
-  }, 'postMessage from ServiceWorker to Client');
+  }, 'postMessage from ServiceWorker to Client.');
