### Describe your project's tooling

### Describe the problem

Emulator TwitterAuthProvider.credentialFromResult always returns null

### Steps and code to reproduce issue

The following code works without using emulator

```
try {
const providerTwit = new TwitterAuthProvider();
providerTwit.setCustomParameters({ "lang" : "es" });
const ucTwit = await signInWithPopup(auth, providerTwit);
console.log("==TWITTER==");
console.Log(ucTwit);
const twitterCred = TwitterAuthProvider.credentialFromResult(ucTwit);
console.log("==TWITTER CRED==");
console.log(twitterCred);
} catch(e) {
console.error(e);
}
```

With the emulator, `twitterCred` always returns null. This problem doesn't happen with the Facebook, GitHub, or Google auth providers.
