WebAuthenticationBroker.AuthenticateAsync Window Issues

[EWSoftware]

When using WebAuthenticationBroker.AuthenticateAsync, it appears that the web view control has a transparent background which can make some of the content unreadable if the dark theme is in use. Also, the window isn't resizable. Can it be updated to support setting a background color and make the window resizable or perhaps set the initial size?

Using NativeWebDialogFactory allows setting the initial size and indicating that the user can resize the window. Using TryGetWindow allows setting the background color. However, although it allows resizing, the web view control maintains its initial size and doesn't grow or shrink along with the window when resized. Resizing isn't an issue for me now that I can set the initial size, but I'll leave this open in case the resizing issue is a bug.

var authOptions = new WebAuthenticatorOptions(new Uri(authorizationUrl), new Uri(redirectUrl))
{
    NativeWebDialogFactory = () =>
    {
        var dialog = new NativeWebDialog
        {
            // It does allow resizing but the web view control doesn't resize along with the window.
            // It keeps the initial size set below.
            CanUserResize = true,
            Title = "Authorization Login"
        };

        dialog.Resize(1000, 800);

        // Set the background to white to avoid the issue with the dark theme where the content
        // is almost unreadable.
        dialog.TryGetWindow()?.Background = new SolidColorBrush(Colors.White);

        return dialog;
    }
};
