window.navigator.serviceWorker.register = (...args) => {
                const url = args[0];

                if (typeof url === 'string') {
                    if (WindowSandbox._isSecureOrigin(url)) {
                        // NOTE: We cannot create an instance of the DOMException in the Android 6.0 and in the Edge 17 browsers.
                        // The 'TypeError: Illegal constructor' error is raised if we try to call the constructor.
                        return Promise.reject(isAndroid || isMSEdge && browserVersion >= 17
                            ? new Error('Only secure origins are allowed.')
                            : new DOMException('Only secure origins are allowed.', 'SecurityError'));
                    }

                    args[0] = getProxyUrl(url, { resourceType: stringifyResourceType({ isScript: true }) });
                }

                if (args[1] && typeof args[1].scope === 'string') {
