WPF TextBlock Textwrapping导致文本被剪切

Question

我有一个WPF TextBlock导致文本被剪裁。生成的文本长度为2到3行。有时第一行的底部会被剪裁。

以下是XAML。问题出在TextBlock上：

<Grid x:Name="background">
<Grid.ColumnDefinitions>
    <ColumnDefinition Width="Auto" />
    <ColumnDefinition />
    <ColumnDefinition Width="Auto" />
</Grid.ColumnDefinitions>
<Rectangle Width="24"
    Height="24"
    Margin="10,5"
    Fill="{StaticResource ExclaimationIcon}" />
<TextBlock Grid.Column="1"
    Margin="5"
    VerticalAlignment="Center"
    Text="{Binding Message}"
    TextWrapping="Wrap" />
<Button Grid.Column="2"
    Margin="5"
    VerticalAlignment="Top"
    Command="{Binding Clear}"
    Padding="3"
    Style="{StaticResource HiddenButtonStyle}"
    Visibility="{Binding AllowedToClear,
    Converter={StaticResource ShowOnTrue}}">
    <Image Width="12" Height="12"
        Source="/AppliancePluginLibrary;component/AdminComponents/Assets/Delete.png" />
</Button>
</Grid>

将TextOption.TextFormattingMode设置为Display可修复此问题。
