<ContentPage xmlns="http://schemas.microsoft.com/dotnet/2021/maui"
             xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
             x:Class="MauiIosNestedGridIssue.MainPage">
    <Grid>
        <ContentView HorizontalOptions="End">
            <Grid RowDefinitions="Auto,Auto" VerticalOptions="Start" Background="LightPink">
                <Image Aspect="Center" HeightRequest="17.5">
                    <Image.Source>
                        <FontImageSource Glyph="A"/>
                    </Image.Source>
                </Image>
