         <ol>
-          <li>Create a trusted event <var>e</var> that uses the {{FetchEvent}} interface, with the event type <code><a href="#service-worker-global-scope-fetch-event">fetch</a></code>, which does not bubble.</li>

+          <li>Initialize <var>e</var>’s {{Event/type}} attribute to "<code>fetch</code>".</li>
+          <li>Initialize <var>e</var>’s {{Event/cancelable}} attribute to true.</li>

Note that fetch and foreignfetch are cancelable. When they're canceled without calling respondWith(), it returns network error. See https://github.com/w3c/ServiceWorker/issues/51#issuecomment-51172079.

FYI. install and activate are not cancelable as you pointed.
