WinUI. Auto-sized Grid row containing ScrollView containing a Rectangle ignores explicit HeightRequest on the Rectangle.

[Keflon]

Description

Given the following xaml:

<ContentPage xmlns="http://schemas.microsoft.com/dotnet/2021/maui"
             xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
             x:Class="MauiGridScrollBug2.MainPage">
    
    <Grid RowDefinitions="*,*">
        <ScrollView Grid.Row="0">
            <Rectangle HeightRequest="600" BackgroundColor="Blue"/>
        </ScrollView>
        <ScrollView Grid.Row="1">
            <Rectangle HeightRequest="600" BackgroundColor="Yellow"/>
        </ScrollView>
    </Grid>

</ContentPage>

Expected result is 2 grid rows each with a Rectangle that can be scrolled up and down.

Actual result for WinUI - the Rectangle instances are minimal height.

Steps to Reproduce

1. Create a File->New MAUI app.
2. Replace the MainPage.xaml content with this:

<Grid RowDefinitions="*,*">
    <ScrollView Grid.Row="0">
        <Rectangle HeightRequest="600" BackgroundColor="Blue"/>
    </ScrollView>
    <ScrollView Grid.Row="1">
        <Rectangle HeightRequest="600" BackgroundColor="Yellow"/>
    </ScrollView>
</Grid>

3. Remove the click-handler in MainPage.xaml.cs
4. Run the WinUI app.

Did you try other controls inside of the ScrollCiew instead of a Shape? Like a label with HeightRequest?

Button and Label instances work as expected. Both were tried with same HeightRequest of 600.
