Description

When using a Shell and navigating to a page which has logic to focus an entry on loaded, the page gets moved partially outside the viewport. This only happens on iOS and when the pages is on the Navigation Stack.

When using the same pages with a NavigationPage everything works as expected.

Steps to Reproduce

1. Create new empty MAUI project.
2. Add a new ContentPage which has an entry. Add a handler to the Page.Loaded event which calls Focus method on the Entry.
3. Add a button to the MainPage which pushes the new Page on the NavigationStack when pressed.
4. Start the app, press the button on the MainPage and leave the entry on the new page.

Expected outcome:
The Page is shown correctly.

Actual outcome:
The Page gets moved parially outside the viewport.

    TestEntry.Focus();
  });
}
