This feature will cause service workers that handle navigation requests by calling `fetch(evt.request)` to use the origin and redirect chain from `FetchEvent.request`. Previously this information was always set to the service worker's origin with no redirect chain. This information is used to control the origin header and SameSite cookies sent with the request to the server.
