Reproduction for iOS

Demonstrates a Master-Detail page bug where the "Page button" as shown in the docs (https://developer.xamarin.com/guides/xamarin-forms/application-fundamentals/navigation/master-detail-page/) disappears on iOS if you insert a Page before the Current page in the Navigation stack of the Detail, and then PopAsync to that new page.

Android handles the situation just fine - the "Page button" remains present after the PopAsync. The iOS reproduction does not show what it should (in this case, the title of the Master page, since there is no default icon for that platform).

I have tried many variations on this, with and without adding icons for the page button on iOS. None of them behave differently. As this is the smallest reproduction, I have left it in this state.

This bug is possibly related to https://bugzilla.xamarin.com/show_bug.cgi?id=41085 as well. Both bugs are for applications that have similar structure with the NavigationPage in the detail being used directly.
