Command.Subscribe treat Exception

[melopigmaster]

  _command = ReactiveCommand.Create(Observable.Return(true));
                     _command .Subscribe(x => { throw new Exception("error"); });

public partial class App : Application
     {
         protected override void OnStartup(StartupEventArgs e)
         {
             Current.DispatcherUnhandledException += CurrentOnDispatcherUnhandledException;
         }
}

   private void CurrentOnDispatcherUnhandledException(
             object sender,
             DispatcherUnhandledExceptionEventArgs dispatcherUnhandledExceptionEventArgs)
         {
         }

    UserError.RegisterHandler(exc =>
             {
                 return Observable.Return(RecoveryOptionResult.CancelOperation);
             });

In version 5 exception is caught here

  RxApp.DefaultExceptionHandler = Observer.Create<Exception>(exc =>
             {

             });

Now they do not come back

The fact that they were caught in v5 was solely by coincidence, exceptions thrown in Subscribes aren't handled by Rx. ThrownExceptions catches the OnError from the Observable created via CreateAsyncObservable, or the exception thrown by the block in CreateAsyncTask

I think that should come in CurrentOnDispatcherUnhandledException but do not come
