[Memo] Grid Measure Issue on DialogView

[muak]

The two-column layout does not seem to calculate the size correctly.

<Grid ColumnDefinitions="*,Auto"
        ColumnSpacing="0">
                                        

    <Label Grid.Column="0"
            Text="{Binding}"
            FontAttributes="Bold"
            VerticalOptions="Center"
            Margin="0,16,0,16"/>

    <Image Grid.Column="1"
            Source="dotnet_bot"
            WidthRequest="24" HeightRequest="24"
            VerticalOptions="Center"
            Margin="0,0,8,0" />

    <BoxView
        Grid.Column="0" Grid.ColumnSpan="2"
        HeightRequest="1" Color="Gray"
        VerticalOptions="End" HorizontalOptions="FillAndExpand" />
</Grid>

This can be resolved by explicitly specifying RowDefinitions="Auto".

<Grid ColumnDefinitions="*,Auto"
        RowDefinitions="Auto"
        ColumnSpacing="0">
