Angular Service Worker breaks on iframe fallback#51

In case of hidden iframe fallback, the Angular Service Worker catches the download URL and tries to route it within the SinglePageApplication. Since the download filename is not matching to any route, this attempt results the following error: ERROR Error: Uncaught (in promise): Error: NG04002 noMatchError The problem discussed here in general: https://stackoverflow.com/questions/60431490/angular-router-is-catching-url-from-iframe Fortunately Angular has a URL parameter, to prevent the SW to process the request. ?ngsw-bypass=true An option that can trigger "ngsw-bypass" parameter would be very useful.
