I have another repro that I believe to be the same bug: https://github.com/Redth/MauiRepro_RefreshScrollRepro in my case it seems largely problematic on Mac/iOS

Confirmed that this regressed between https://github.com/dotnet/maui/compare/8.0.0-preview.1.7762..7.0.92. https://github.com/dotnet/maui/pull/11357 seems sus.

Where is the Border in the visual tree? Inside the ScrollView? I have added several Borders and with the latest version the SizeChanged event of the ScrollView is triggered.
