Description

Standard code (from example):

  try {

    await Firebase.initializeApp(options: firebaseOptions);
    analytics = FirebaseAnalytics.instance;
    observer = FirebaseAnalyticsObserver(analytics: analytics!);
    await analytics?.logEvent(name: 'initialize_app', parameters: {
      'app_name': appName.toLowerCase(),
      'app_version': appVersion.toLowerCase(),
      'app_platform': getPlatformName(),
    } );

  } catch (e) {
    print('initFirebaseAnalytics: ' + e.toString());
  }

If app running from direct address, all working. If app running in iframe tag, analytics does not sends any events (and no errors reported)
