Description

When you add code to the App Shell's OnSizeAllocated the code is executed when the app runs on iOS but the event is not executed when running on Android.
It works for an individual page but not for the Appshell.cs event

Steps to Reproduce

In new Maui App
Override OnSizeAllocated event in AppShell.cs
Overider OnSizeAllocated in Mainpage.xaml.cs

Expected Result
OnSizeAllocated event should for for both the app shell page and the main page

Actual Result
On iOS it for for both AppShell and MainPage (correct)
On Android it only fires for the MainPage and fails to fire for AppShell
