Settings Dialog and Popup Menu Not Show in flwpf:FlyleafME

currently I use 3.7.28 version. in my app, I use bellow <flwpf:FlyleafME x:Name="flyleafControl" Player="{Binding Player}"/> which load FlyleafLib.Controls.WPF\Themes\FlyleafME.xaml as default Video View I don`t want use your custom Video View in MainWindow.xaml that contains more feature like Messages, Status, Subtitles everything works fine.

now I update to 3.7.50. with your custom Video View in MainWindow.xaml everything is OK. below code is your code in MainWindow.xaml:

<!--Video View-->
                    <Grid Grid.Row="1" x:Name="PART_ContextMenuOwner" ContextMenu="{StaticResource PopUpMenu}">
                        <Grid.Style>
                            <Style TargetType="{x:Type Grid}">
                                <Setter Property="Visibility" Value="Collapsed" d:Value="Visible"/>

                    </Grid>

but in this new version (3.7.50) when I replace your custom Video View with <flwpf:FlyleafME x:Name="flyleafControl" Player="{Binding Player}"/> Settings Dialog and Popup Menu does not show. other feature works fine. in 3.7.28 version this problem does not exist. if you want, I can send you my project!!! To understand my problem better

few days ago I debug your code and I find out FlyleafME.cs in Initialize() method:

popUpMenu       = ((FrameworkElement)Overlay.Template.FindName("PART_ContextMenuOwner", Overlay))?.ContextMenu;
dialogSettings  = (DialogHost)Overlay.Template.FindName("PART_DialogSettings", Overlay);

both variable evaluate with NULL Reason? I can`t understand

below code is your FlyleafME.xaml
