`navigator.serviceWorker.controller` must return a [ServiceWorker][1] object
representing the [active worker][2] that currently handles resource requests
for the document. `navigator.serviceWorker.controller` returns `null` if the
current document was not [created under a Service Worker][3] (See step 6-1 of
[_OnFetchRequest][3] algorithm) or the request is a force refresh
(shift+refresh).
