Restrict Internal Login Browser / Window to Portrait mode

[stezma]

Library - Microsoft.Idendity.Client (V) 4.0.0
Platform - Xamarin Forms.

In my app I am using Embedded WebView for login ( .WithUseEmbeddedWebView(true)). The issue I am facing here is,
I am restricting my app to work only on Portrait Mode through code. But even though I restrict it through code, Only on login WebView(Embedded WebView) it is not working. The orientation is not locked for Azure AD B2C login Page.
Along with that,

After typing the user name Password, if the orientation changes it clears the text fields that already filled. Which is quite annoying.

Please Fix.!!!!

This is the code i am using

Method to Sign-In

 private async Task<UserContext> SignInInteractively()
        {
            IEnumerable<IAccount> accounts = await PCA.GetAccountsAsync();
            AuthenticationResult ar = await PCA.AcquireTokenInteractive(B2CConstants.Scopes)
                .WithAccount(GetAccountByPolicy(accounts, B2CConstants.PolicySignUpSignIn))
                .WithParentActivityOrWindow(ParentActivityOrWindow)
                .WithUseEmbeddedWebView(true)
                .ExecuteAsync();

            var newContext = UpdateUserInfo(ar);
            return newContext;
        }

Restricting the orientation

 [Activity(Label = "UserDetailsClient",
        Icon = "@drawable/icon",
        Theme = "@style/MyTheme",
        MainLauncher = true, ConfigurationChanges = ConfigChanges.ScreenSize | ConfigChanges.Orientation, ScreenOrientation = ScreenOrientation.Portrait)]
    public class MainActivity : global::Xamarin.Forms.Platform.Android.FormsAppCompatActivity
    {

Is it possible to lock the orientation of Embedded WebView in this release. I can see the username / password clearing issue has been resolved. What about orientation?
