**Actual behavior:** Clicking on the taskbar icon window does not respond

**Expected behavior:** Window display restored

**Minimal repro:**
```
public partial class MainWindow : Window
{
public MainWindow()
{
InitializeComponent();
Loaded += MainWindow_Loaded;
}

private WindowA _windowA = null;
private WindowB _windowB = null;
private void MainWindow_Loaded(object sender, RoutedEventArgs e)
{
_windowA = new WindowA();
_windowA.Owner = this;
_windowA.Show();
_windowB = new WindowB();
_windowB.Owner = _windowA;
_windowB.Show();
}
}
```
