Current behavior

MainCommand does not appear when setting the icon on a global style, no error is shown it just doesn't render. When removing it from the style, appears behaves as expected.

SideNote: This is using Native renderer

Expected behavior

Main Command should appear and navigte back when backstack is not empty even if the icon is set from style.

How to reproduce it (as minimally and precisely as possible)

1. Create a new Uno Platform application with this features:
2. Create an style for main command AppBarButton
3. Set a global default style for NavigationBar control and set Style for MainCommand
4. Run Application and navigate to second page
5. back button doesn't appear (if icon is removed main command appears and works correctly)
