I created a minimal reproduction: https://github.com/twixthehero/account-delete-test

1. git clone git@github.com:twixthehero/account-delete-test
2. cd account-delete-test && npm install
3. Configure FirebaseAppConfig in src/app/app.module.ts
4. Run npm start
5. Open http://localhost:4200.
6. Click 'Register' tab, create a new account.
7. Once logged in, click 'delete account'.
