Description

Correct width and height not being reported for a content view that is placed inside of AppShell FlyoutContent

Steps to Reproduce

1. Create a new MAUI App
2. Change FlyoutBehavior to "Flyout"
3. Add a Custom ContentView and override OnSizeAllocated method
   protected override void OnSizeAllocated(double width, double height)
   {
   base.OnSizeAllocated(width, height);
   // BUG: Actual size never reported :(
   Console.WriteLine($"====> W {width} H {height}");
   }
4. Add the custom content view as a flyout in appshell
   <Shell.FlyoutContent>
   <local:MainMenuView />
   </Shell.FlyoutContent>

When running the app the method is invoked twice
once with '-1' values and another time with '0' values - never the actual size.
