SignInOptions do not render on sign-in screen when logging out after making API call

I am building an app using the react web UI and I've run into a very strange issue: whenever I logout of my app _after_ I perform some type of API call (in this case, just a simple CRUD operation to the DB or uploading a photo to storage) I return to the sign-in screen however the `signInOptions` don't render via `.

If I logout _without_ making any API call, the `FirebaseAuth` component and `signInOptions` render normally.

In both cases the `uiConfig` and `app.auth` are being passed properly to ``. I have no idea what to make of this.

If it helps, here is my auth screen component:

```
import * as React from 'react';
import * as firebaseui from 'firebaseui';
import * as firebase from 'firebase/app';
import FirebaseAuth from 'react-firebaseui/FirebaseAuth';
import * as app from '@/app';

class Authenticate extends React.Component {
render() {
const uiConfig = {
signInSuccessUrl: '/',
signInOptions: [
firebase.auth.EmailAuthProvider.PROVIDER_ID,
firebase.auth.GoogleAuthProvider.PROVIDER_ID
],
credentialHelper: firebaseui.auth.CredentialHelper.NONE
}

return

export default Authenticate;
```

まず Authenticate component に記述されている logout フローを再現し、API 呼び出し後の logout と、API 呼び出し前の logout を比較します。認証状態の変更後に FirebaseAuth が remounting と sign-in オプションをどのように処理するかを確認します。両方の場合で設定済みのオプションがレンダリングされれば完了です。
