Android/Windows When the app starts, the CatPage is shown, which shows collection of cats. Now when you click on a cat, you navigate to the cats'Detailspage. Now you navigate back by clicking the back button. Now click again on the same cat that was previously selected. Nothing happens. Expected: Seeing the cats'Detailspage again.

Repro steps: Run the app. Select a cat. (=> View changes to DetailsView). Navigate back. Try to select same cat again. => Nothing happens.
