[PopupButton] Popup will close even if StaysOpen is true

Hello,

Are you sure you're on the version you listed above?  I'm not seeing it close when showing a modal dialog.

That being said, we did notice an issue where the popup was closing on focus loss in a certain scenario and have fixed that for the upcoming v22.1.3 maintenance release.

Hello,

Thank you for replying.

Though I checked it with 22.1.3-beta.9, the issue was not solved.

You can see the issue by the following modification of SampleBrowser source code.
Would you please check it?

• ActiproSoftware.ProductSamples.SharedSamples.QuickStart.PopupButtonIntro
  MainControl.xaml
    - popupButtonWithPopup
      - Remove PopupContentTemplate property
  
  MainControl.xaml.cs
    - OnPopupButtonPopupOpening
      - Add the following code.
  

  var button = new Button() { Content = "Show Dialog" };
  button.Click += (_, __) =>
  {
  	var window = new Window();
  	window.ShowDialog();
  };
  popupButtonWithPopup.PopupContent = button;​

Thank you for the repro steps.  The change we made yesterday for the upcoming maintenance release appears to have fixed this issue. 

If I set StaysOpen="True", I didn't see the popup close in our latest codebase when opening the dialog.  But if I reverted that recent code change, I was able to reproduce the problem.
