Description

Empty space appears at the bottom of the page when navigating from a page which has the tab bar hidden to a page which has the tab bar visible.

Steps to Reproduce

1. Create a new MAUI project with a shell
2. Create Tab page with the following layout:
   Root Grid layout with SafeAreaEdges="None" and place another Grid (with default SafeAreaEdges which is Container) inside with a long ScrollView in it.
3. Add the Tab page 2 or more time to the shell as a tab to make the tab bar appear.
4. Create another page which has the tab bar hidden HiddenTabBarPage.
5. Setup navigation so the Tab page can navigate next to HiddenTabBarPage. For example:
   Shell.Current.Navigation.PushAsync(new HiddenTabBarPage());
6. Launch the app on Android 36 API.
7. Navigate to the next page HiddenTabBarPage and go back

Actual result:
Empty space appears between the nested Grid and the tab bar.
