IsSelectionActive cleared when RowDetailsTemplate clicked

Question

I have a datagrid with row details. When I click in the row details the IsSelectionActive on the datagrid is cleared. Now this only happens on some of my datagrids while others using the exact same styles and templates exabit the correct behavior. Here is my xaml for the DataGridRow. when I click on the details view with the error the background of the detail changes to yellow. Also my IsSelected color is cleared however the IsSelected property is always set.

    <Style TargetType="{x:Type DataGridRow}">
    <Style.Triggers>
        <MultiDataTrigger>
            <MultiDataTrigger.Conditions>
                <Condition Binding="{Binding IsSelected}" Value="True"/>
                <Condition Binding="{Binding RelativeSource={RelativeSource Mode=FindAncestor, AncestorType={x:Type DataGrid}}, Path=IsSelectionActive }" Value="False"/>
            </MultiDataTrigger.Conditions>
            <MultiDataTrigger.Setters>
                <Setter Property="Background" Value="Yellow"/>
                <Setter Property="Foreground" Value="Black"/>
            </MultiDataTrigger.Setters>
        </MultiDataTrigger>

        <MultiDataTrigger>
            <MultiDataTrigger.Conditions>
                <Condition Binding="{Binding IsSelected}" Value="True"/>
                <Condition Binding="{Binding RelativeSource={RelativeSource Mode=FindAncestor, AncestorType={x:Type DataGrid}}, Path=IsSelectionActive }" Value="True"/>
            </MultiDataTrigger.Conditions>
            <MultiDataTrigger.Setters>
                <Setter Property="Background" Value="{DynamicResource PrimaryColor}"/>
                <Setter Property="Foreground" Value="White"/>
            </MultiDataTrigger.Setters>
        </MultiDataTrigger>
    </Style.Triggers>
</Style>

Upon further research I have determined this bug occurs when the datagrid is wrapped in a ScrollViewer. In my case I have a dynamic number of different datagrids that must display in a single view which can then be scrolled. As soon as I replace the ScrollViewer with A StackPanel the bug goes away, but I need the ScrollViewer.
