Steps to reproduce

1. run fresh app with auth state as signed out.
2. select registration with phone
3. enter a test phone number
4. click the done/submit button on the keyboard
5. enter the test validation code
6. click the done/submit button on the keyboard

### Expected Behavior

the OTP verification starts and the user gets signed in.

Actual Behavior

sometimes the verification does not start (blocked by something? I am not certain) and another click (sometimes multiple clicks) on verify button is required to verify OTP. in other instances, I have to go back to main login page and retry entering the phone number and request another OTP. I notice that this happens when the app is launched fresh and not when signed out and then trying to sign in again.

Additional Information

I used this with a test phone number that was added to firebase authentication. When I try the same with a real phone number I end up receiving multiple SMS messages from Firebase. This makes the auth costs almost double for my project.

Here is a screen recording for the issue. in the video you notice the first sign in does not pick the OTP confirm button click and I had to click verify. In the second attempt (in the same screen recording) the OTP confirm button works right away. https://github.com/firebase/FirebaseUI-Flutter/assets/12709757/c6508b8c-9100-4f1e-9ad4-792811ffbb8d
