IsSharedSizeScope属性的WPF问题

Question

如果在网格(父)级别将IsSharedSizeScope设置为true，并将StackPanel设置为子级，则IsSharedSizeScope属性将不起作用，但当我删除StackPanel时，它会起作用。我在试着理解我做错了什么。任何帮助都将不胜感激。

TextBlocks上的Grid.Column无关紧要，因为它们并不直接位于Grid内部。清晰的问题陈述是解决方案的一半:将TextBlocks直接放入网格中(在适当的行中)。

<Grid Grid.IsSharedSizeScope="True">

    <Grid.RowDefinitions>
        <RowDefinition Height="Auto" />
        <RowDefinition Height="Auto" />
        <RowDefinition Height="Auto" />
        <RowDefinition Height="Auto" />
        <RowDefinition Height="Auto" />
        <RowDefinition Height="Auto" />
    </Grid.RowDefinitions>

    <Grid.ColumnDefinitions>
        <ColumnDefinition Width="Auto" SharedSizeGroup="A"/>
        <ColumnDefinition Width="Auto" SharedSizeGroup="A"/>
        <ColumnDefinition Width="Auto" SharedSizeGroup="A" />
    </Grid.ColumnDefinitions>

    <TextBlock Grid.Row="1" Grid.Column="0" Text="Detect charger" Margin="3" HorizontalAlignment="Center" VerticalAlignment="Center"/>
    <TextBlock Grid.Row="1" Grid.Column="1" Text="Ok" Margin="3" HorizontalAlignment="Center" VerticalAlignment="Center"/>

    <TextBlock Grid.Row="2" Grid.Column="0" Text="Configure meter" Margin="3" HorizontalAlignment="Center" VerticalAlignment="Center"/>
    <TextBlock Grid.Row="2" Grid.Column="1" Text="Ok" Margin="3" HorizontalAlignment="Center" VerticalAlignment="Center"/>

    <TextBlock Grid.Row="3" Grid.Column="0" Text="Activate charger" Margin="3" HorizontalAlignment="Center" VerticalAlignment="Center"/>
    <TextBlock Grid.Row="3"  Grid.Column="1" Text="Ok" Margin="3" HorizontalAlignment="Center" VerticalAlignment="Center"/>

    <TextBlock Grid.Row="4" Grid.Column="1" Text="Upgrade version" Margin="3" HorizontalAlignment="Center" VerticalAlignment="Center"/>
    <TextBlock Grid.Row="4" Grid.Column="2" Text="Ok" Margin="3" HorizontalAlignment="Center" VerticalAlignment="Center"/>
</Grid>
