Description

If you call the web authentication login method too fast after app is brought to the foreground, the login fails with the following error:

WebAuthenticationException (OTHER: An unexpected error occurred. CAUSE: Error Domain=com.apple.AuthenticationServices.WebAuthenticationSession Code=3 "The UIWindowScene for the returned window was not in the foreground active state." UserInfo={NSDebugDescription=The UIWindowScene for the returned window was not in the foreground active state.}) [K] #0 MethodChannelAuth0FlutterWebAuth.invokeRequest (package:auth0_flutter_platform_interface/src/method_channel_auth0_flutter_web_auth.dart:45:7) <asynchronous suspension> #1 MethodChannelAuth0FlutterWebAuth.login (package:auth0_flutter_platform_interface/src/method_channel_auth0_flutter_web_auth.dart:21:9) <asynchronous suspension> #2 WebAuthentication.login (package:auth0_flutter/src/mobile/web_authentication.dart:89:25) <asynchronous suspension> #3 AuthService.acceptInvite (package:knowby_pro/features/auth/state/auth_service.dart:368:27) <asynchronous suspension>

We are only able to get around this by adding a fake delay before calling the login method.

Reproduction

1. Create a new flutter route in the example which calls web auth login as soon as the route loads
2. Deeplink to that route when app is in the background (iOS)
