WPF TextBlock Textwrapping Causes Text to be Clipped

问题

I have a WPF TextBlock which is causing the text to be clipped. The resulting text is 2 to 3 lines long. Sometimes the bottom of the first line is clipped.

Following is the XAML. The problem is with the TextBlock:

<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>

Setting the TextOption.TextFormattingMode to Display fixed this problem.
