+- A same-origin fetch request for a media element (for example, using a {{htmlelement("video")}} element) will now pass through a service worker without stripping the {{httpheader("Range")}} header.
+  Previously the `Range` header was only preserved in same-origin CORS requests, made by adding the `crossorigin` attribute (`<video crossorigin>`).
+  Note that `Range` headers are still stripped from cross-origin no-cors requests passing through a service worker.
