MAUI: WebView inside VerticalStackLayout and ScrollView does not expand (iOS)

Question

Following simplified XAML works fine in Xamarin.Forms and Maui:

<ScrollView HorizontalScrollBarVisibility="Never">
    <StackLayout>
        <WebView x:Name="WebView" VerticalOptions="FillAndExpand">
            <WebView.Source>
                <HtmlWebViewSource Html="{Binding html}"/>
             </WebView.Source>
        </WebView >
    </StackLayout>
</ScrollView>

Now in Maui because "FillAndExpand" and expand is obsolete and might not work in the future I tried setting it to "Fill", but then WebView doesn't get resized.

So I tried replacing StackLayout with VerticalStackLayout, but still doesn't expand:

<ScrollView HorizontalScrollBarVisibility="Never">
    <VerticalStackLayout>
        <WebView x:Name="WebView" VerticalOptions="Fill">
            <WebView.Source>
                <HtmlWebViewSource Html="{Binding html}"/>
             </WebView.Source>
        </WebView >
    </VerticalStackLayout>
</ScrollView>

So my question is - why does obsolete property works fine, but not the new one? And more importantly, how can I fix this issue?

You can use Grid instead of VerticalStackLayout which will expand automatically:

<ScrollView HorizontalScrollBarVisibility="Never">
    <Grid>
        <WebView x:Name="WebView">
            <WebView.Source>
                <HtmlWebViewSource Html="{Binding html}"/>
             </WebView.Source>
        </WebView >
    </Grid>
</ScrollView>
