Reproducing Project

=== Overview ===
Nesting a master detail page in a tabbed layout on UWP can cause an exception when used with the modal page stack. Specifically if you have a master-detail page as a child of a TabbedPage, navigate to another child of the tabbed page and open a modal page, when you return from the modal page stack the master-detail page causes an exception when it's bounds are calculated. A workaround I have found for this problem is to set IsShowing on the page to false in the OnDisappearing method of the MasterDetail page.

I've attached a reproducing project

=== Steps to Reproduce  ===
Run the attached repro project

1. Starts on the main page with a master-detail page nested within a tabbedpage
2. Navigate to "Page 2"
3. Click the button to open a modal page
4. Click the button on the modal page to return

=== Expected Behavior ===
The page stack should return to its location and state before pushing the modal page

=== Actual Behavior ===
An exception occurs:

System.ArgumentException: width
   at Windows.Foundation.Size..ctor(Double width, Double height)
   at Xamarin.Forms.Platform.UWP.MasterDetailControl.get_DetailSize()
   at Xamarin.Forms.Platform.UWP.MasterDetailPageRenderer.UpdateBounds()
   at Xamarin.Forms.Platform.UWP.MasterDetailPageRenderer.OnControlLoaded(Object sender, RoutedEventArgs routedEventArgs)
