[WPF/MapControl] MapControl is on top of every other control

[meJevin]

When using MapControl I am unable to place any other controls in WPF on top of it. It seems to be on top of everything for some reason.

I've not seen a version where this is fixed.

Steps to Reproduce

Steps to reproduce the behavior:

1. Go to Reproduction repo link
2. Go to Source folder
3. Open MapControlBug.sln solution
4. In MainWindow.xaml verify that the button with content Hello is rendered over the MapControl in the XAML previewer.
5. Run the application and verify that MapControl is rendered on top of the aforementioned Button

Expected behavior

MapControl should respect z index of other controls

I get the same issue with MediaPlayerElement . I assume it is the case for all UWP controls hosted on WPF? Is there any work around?

[michael-hawker]

I believe this is a general airspace issues, I thought Winforms host behaved the same way? Not sure if there's anything to be done. Thought there was a note somewhere about this... @marb2000?

You are right @michael-hawker it looks like air-space issues.
