HighlightTextBlock的HighlightBrush不能响应DataTrigger

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）

Additional context

No response

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.
