Reproducible in sample app?

  • This bug can be reproduced in the sample app.

Steps to reproduce

1. Use the sample I've created:
[https://github.com/CesGan/ListDetails_BackButton_NotWorking]
2. Run the app.
3. On the NavigationView navigate to ListDetails
4. Resize the width app so that the ListDetails only shows the List.
5. Navigate to one of the details "name" or "name2"
6. The back button should be enabled. Click on it.
7. Exception is throwed.

There's a way for this to work.
Follow the same steps as above but before step 3 you click on the "Settings" button. This will set the frame.CanGoBack as true and thus enabling us to use the back button without throwing an exception.

Expected behavior

I expected to follow the steps mentioned above and no exception to be throwned.
