Service Worker Automatically Skips Waiting

[NoelAbrahams]

Hi

Edge version: 42.17134.1.0
Edge HTML: 17.17134

In Edge a newly installed Service Worker is being automatically activated on refresh (ie equivalent to always calling skipWaiting).

The following bit of code should alert whenever serviceworker.js is modified and the browser is refreshed:

navigator.serviceWorker.ready.then(function (registration) {
      console.log('ready');

      if (registration.waiting) {
           alert('waiting');
       }
});

This never alerts in Edge, but does in Chrome and FireFox.

Hey thanks for the report @NoelAbrahams ! Unfortunately this is a web API issue rather than a JS engine issue. Can you open an issue on EdgeHTML issue tracker so the right folks can look at them?
