**React File:**
```
import StyledFirebaseAuth from "react-firebaseui/StyledFirebaseAuth";
import firebase from "firebase/app";
import "firebase/auth";
import initFirebase from "../utils/auth/initFirebase";

initFirebase();

const firebaseAuthConfig = {
signInFlow: "popup",
signInOptions: [
{
provider: firebase.auth.PhoneAuthProvider.PROVIDER_ID,
requireDisplayName: false,
recaptchaParameters: {
size: "invisible", // 'invisible' or 'compact'
},
},
],
signInSuccessUrl: "/",
credentialHelper: "none",
callbacks: {
signInSuccessWithAuthResult: async ({ user }, redirectUrl) => {

},
};

const FirebaseAuth = () => {
return (

);
};

export default FirebaseAuth;

```

I used this NextJS repo: https://github.com/vercel/next.js/tree/canary/examples/with-firebase-authentication

Comienza con la configuración de React proporcionada y reproduce el error seleccionando un código de país telefónico y haciendo clic fuera del menú desplegable. Inspecciona el stack de firebaseui/dist/esm.js informado alrededor de la ruta de blur del código de país; se considera terminado cuando el menú desplegable puede cerrarse sin el TypeError.
