Applies Private Network Access checks to web workers: dedicated workers, shared workers and service workers. These checks apply to all worker-specific fetches: - initial worker script fetch - fetch within workers - service worker script update fetch If the fetch is from an insecure context, we'd show a warning in DevTools. If the fetch is from a secure context, we'd send a preflight. If the preflight fails, we'll also show a warning in DevTools.
