VerticalOptions cannot be set on a Rectangle in Windows

Description

I'm having a Grid with a fixed size and a background color. Inside that I'm trying to draw a Rectangle from the bottom (like a vertical progress bar). This works as expected in Android. But in Windows the inner rectangle always fills the Grid. Drawing the inner rectangle with a Grid solves the problem.

This is from Windows:

And this is from Android:

The left progress bar is draw with two Grids, the right one with a Grid and a Rectangle.

Steps to Reproduce

1. Create a new MAUI app.
2. Replace the MainPage.xaml with this:

<?xml version="1.0" encoding="utf-8" ?>
<ContentPage xmlns="http://schemas.microsoft.com/dotnet/2021/maui"
             xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
             x:Class="MauiIssues.MainPage">

    <HorizontalStackLayout 
        Spacing="25" 
        Padding="30,30" 
        VerticalOptions="Start"
        >
        <!-- This works fine -->
        <Grid WidthRequest="100" HeightRequest="200" BackgroundColor="{StaticResource Gray600}">
            <Grid  
                HeightRequest="50" 
                VerticalOptions="End" 
                BackgroundColor="{StaticResource Blue100Accent}"
            />
        </Grid>

        <!-- This is fine on Android, but not on Windows -->
        <Grid WidthRequest="100" HeightRequest="200" BackgroundColor="{StaticResource Gray600}">
            <Rectangle
                HeightRequest="50" 
                VerticalOptions="End" 
                BackgroundColor="{StaticResource Blue200Accent}"
            />
        </Grid>
    </HorizontalStackLayout>
</ContentPage>
