two whenany on one object bug

I use reactiveUI for watching properties of DP The code is

/// <summary>
/// Interaction logic for MainWindow.xaml
/// </summary>
public partial class MainWindow : Window
{
    public MainWindow()
    {
        RxApp.DeferredScheduler = DispatcherScheduler.Current;
        InitializeComponent();
        this.WhenAny(i => i.Width, i => i.Value).Subscribe(_ => SomeMethod("Width"));
        this.WhenAny(i => i.Height, i => i.Value).Subscribe(_ => SomeMethod("Height"));
    }

    void SomeMethod(string hello)
    {
        MessageBox.Show(hello);
    }

}

When I resize window by height there is no messagebox But when I resize window by width there is two messageboxes When I comment any of these whenany's it works very well, but with two whenanys work improperly

I know I can watch two propeties by one whenany but I need to watch two dependency properties of differentType by two WhenAny

How can I do this?

Hm. Can you file this bug over at http://github.com/reactiveui/reactiveui/issues? In the meantime, you might have to use a shim, something like:

var changedObservable = new Subject<Unit>();
this.SizeChanged += (o,e) => changedObservable.OnNext(Unit.Default);
