ScrollView doesn't center its content.

[dg2k]

Description

I upgraded my Maui app from net6.0 to net7.0 and having an issue with ScrollView as it doesn't center its content anymore. I use Grid layout to position Labels and Button and ScrollView is used for vertical scrolling. With ScrollView XAML commented out, the view rendering is perfect as it should be.

It works fine on Windows and the issue is on Android. I haven't tested on other platforms.

UPDATE: There is a minor issue with WinUI as well -- if Margin and/or Padding attributes are added to StackLayout containing an Image, the layout gets distorted. The uploaded Demo will explain this clearly with added comment.

Steps to Reproduce

1. Create Grid Layout and position some Labels and Button(s) controls to show as centered.
2. Add the Grid to ScrollView control.

Updated with a link to a publicly accessible GitHub demo project.
The project, when running, shows explanatory notes. The same comment text is in MainPage.xaml.
