OPTIONS request reported as GET

[anthumchris]

Should HTTP OPTIONS requests be accessible and available within a SW's fetch event?
OPTIONS requests are currently reported as GET requests even though the browser sends an HTTP OPTIONS request.

sw.js

self.addEventListener("fetch", function (event) {
  console.log(event.request.method, event.request.url);
});

app.js

navigator.serviceWorker.register('./sw.js')
fetch('https://example.com', {
  headers: {
    'force-cors-preflight': 'foo'
  }
});

Service worker interception occurs before any CORS preflight is made. AFAIK there is no way to get a FetchEvent for a CORS preflight.
