The base URL of stylesheets is now the response URL of the stylesheet rather than the request URL. These are only different if a service worker provided the response. If the service worker does respondWith(fetch(url)), the base URL becomes url. Also, to align with the specification, stylesheets that (a) failed to load due to network error, or (b) loaded via a redirect from cross-origin back to same-origin are considered cross-origin.
