Research direction
Start at the HighlightTextBlock control and reproduce the provided .NET 6/WPF XAML example, comparing the working Foreground DataTrigger with the HighlightBrush and HighlightTextBrush setters. Trace how these properties are declared and applied, then verify that a DataTrigger changes the highlight brushes instead of retaining the explicitly set values.

Description
Describe the bug
使用HighlightTextBlock时发现，即使设置了DataTrigger，HighlightBrush和HighlightTextBrush两个属性依然会使用默认值。
Steps to reproduce the bug
<hc:HighlightTextBlock SourceText="{Binding Header}" QueriesText="{Binding SearchText}" IsEnabled="False"
HighlightBrush="{DynamicResource DarkPrimaryBrush}" HighlightTextBrush="{DynamicResource TextIconBrush}">
<hc:HighlightTextBlock.Style>
<Style TargetType="hc:HighlightTextBlock">
<Style.Triggers>
<DataTrigger Binding="{Binding IsEnabled, RelativeSource={RelativeSource Self}}" Value="False">
<Setter Property="Foreground" Value="{DynamicResource SecondaryTextBrush}"/>
<Setter Property="HighlightBrush" Value="{DynamicResource Gray5Brush}"/>
</DataTrigger>
</Style.Triggers>
</Style>
</hc:HighlightTextBlock.Style>
</hc:HighlightTextBlock>
上面的例子中，IsEnabled==False时，DataTrigger设置的Foreground生效（使用了SecondaryTextBrush），但HighlightBrush没有变化（依然使用DarkPrimaryBrush）
