RefreshView is not initialized properly on Windows platform

[foximoxi]

Description

I encountered an error creating a MAUI Hybrid application where the RefreshView is incorrectly initialized.
But it looks like this is related also to standard MAUI app.

Steps to Reproduce

1. Clone official sample .NET MAUI:
   https://github.com/dotnet/maui-samples/tree/main/8.0/UserInterface/Views/RefreshViewDemo

2. Remove from MainPage.xaml ScrollView and FlexLayout tags which resides inside RefreshView

3. Run app on Windows Machine
   RefreshView indicator animation is not moving and the screen is locked.

4. Add inside RefreshView and it returns to normal behavior!
   If you add BlazorWebView inside RefreshView -> it is not possible to click anything on page

Remarks:

1. In my app when I use RefreshView with BlazorWebView - the web content cannot be interactive because refresh indicator is present blocking inputs even where IsRefreshing/IsEnabled are set to false!

2. Another error -> If you leave inside RefreshView empty ScrollView from example - application crashes with Unhandled exception "Adaptee's content property cannot be null."

3. I tested it on .NET 7 and .NET8 with the same result. All scenarios work on Android.

Only workaround is to add entry inside refresh view. If I add BoxView, Label - does not help.
