[regression/8.0.0-preview.4.8333] Grid ColV isn't constrained to row

[davidortinau]

Description

I have 3 rows in a grid, and the ColV used to take up only the space between, but now it's much to tall and I cannot see row 3 which is a button.

Should look like Android:

Steps to Reproduce

Update csproj to net8 and run it on iOS sim

<Grid RowDefinitions="Auto, *, 66" Margin="20">
        <VerticalStackLayout VerticalOptions="Start" Spacing="8">
            <Label Text="Current Order" Style="{StaticResource LargeTitle}"/>
            <Label Text="{Binding Order.Table, StringFormat='TABLE {0}'}"/>
            <BoxView Style="{StaticResource HRule}"/>
        </VerticalStackLayout>

        <CollectionView Grid.Row="1" ItemsSource="{Binding Order.Items}" VerticalScrollBarVisibility="Never" Background="Transparent">
            <CollectionView.ItemTemplate>
                <DataTemplate x:DataType="models:Item">
                    <Grid ColumnDefinitions="160,60,*" ColumnSpacing="8" Margin="0,8" HeightRequest="70">
                        <Label Text="{Binding Title}" Grid.Column="0" VerticalOptions="Center"/>
                        <Label Text="{Binding Quantity}" Grid.Column="1" VerticalOptions="Center" HorizontalOptions="Start"/>
                        <Label Text="{Binding Price, StringFormat='${0:N2}'}" Grid.Column="2" VerticalOptions="Center" HorizontalOptions="Start"/>
                    </Grid>
                </DataTemplate>
            </CollectionView.ItemTemplate>
            <CollectionView.Header>
                <Grid ColumnDefinitions="160,60,*" Margin="0,8" HeightRequest="40" ColumnSpacing="8">
                        <Label Text="Item" Grid.Column="0" VerticalOptions="Center" Style="{StaticResource Headline}"/>
                        <Label Text="Quantity" Grid.Column="1" VerticalOptions="Center" Style="{StaticResource Headline}"/>
                        <Label Text="Price" Grid.Column="2" VerticalOptions="Center" HorizontalOptions="Start" Style="{StaticResource Headline}"/>
                        <!-- <BoxView Style="{StaticResource HRule}" VerticalOptions="End" Grid.ColumnSpan="3" /> -->
                    </Grid>
            </CollectionView.Header>
        </CollectionView>

        <Grid Grid.Row="2">
            <Button Text="Pay" Command="{Binding PayCommand}" HorizontalOptions="Fill"/>
        </Grid>

    </Grid>
