GridView: ScrollBar background is gray instead of transparent in the Office2019 theme which doesn't match the design

In the Office2019 theme, the RadGridView's ScrollBar elements should have transparent background by design. This is the track's background shown behind the thumb element that allows drag-to-scroll. Currently, the ScrollBars have a gray background.

To work this around, you can define an implicit Style in the App.xaml that targets the GridViewScrollViewer control. Then, set its Background property.

<Application.Resources>
    <ResourceDictionary>
        <ResourceDictionary.MergedDictionaries>
            <ResourceDictionary Source="/Telerik.Windows.Themes.Office2019;component/Themes/System.Windows.xaml"/>
            <ResourceDictionary Source="/Telerik.Windows.Themes.Office2019;component/Themes/Telerik.Windows.Controls.xaml"/>
            <ResourceDictionary Source="/Telerik.Windows.Themes.Office2019;component/Themes/Telerik.Windows.Controls.Input.xaml"/>
            <ResourceDictionary Source="/Telerik.Windows.Themes.Office2019;component/Themes/Telerik.Windows.Controls.GridView.xaml"/>
        </ResourceDictionary.MergedDictionaries>
        <Style TargetType="telerik:GridViewScrollViewer" BasedOn="{StaticResource GridViewScrollViewerStyle}">
            <Setter Property="Background" Value="Transparent"/>
        </Style>
    </ResourceDictionary>
