MaterialDesignFlowDocument style missing?

Is your feature request related to a problem? Please describe.
In order to get better performance compared to RichTextBox, I display a FlowDocumentScrollViewer with a binding to a FlowDocument of the ViewModel.

                <FlowDocumentScrollViewer Document="{Binding FlowDocument1}"
                                          Loaded="FlowDocumentScrollViewer_Loaded"
                                          Unloaded="FlowDocumentScrollViewer_Unloaded">
                </FlowDocumentScrollViewer>

Describe the solution you'd like
I'd like a simple:

                <FlowDocumentScrollViewer Document="{Binding FlowDocument1}"
                                          Loaded="FlowDocumentScrollViewer_Loaded"
                                          Unloaded="FlowDocumentScrollViewer_Unloaded"
                                          Style="{StaticResource MaterialDesignFlowDocument}">
                </FlowDocumentScrollViewer>

Describe alternatives you've considered
Here is the extension method dealing manually with style..

        public static void AppendLogEvents(this FlowDocument flowDocument, IList<LogEvent> logEvents)
        {
            var lastParagraph = flowDocument.Blocks.LastBlock as Paragraph;
            if (lastParagraph == null)
            {
                lastParagraph = new Paragraph();
                flowDocument.Blocks.Add(lastParagraph);
            }

            // Create a new style based on the MaterialDesignTextBoxBase style
            var spanStyle = new Style(typeof(Span));
            //spanStyle.BasedOn = (Style)Application.Current.Resources["MaterialDesignTextBoxBase"];
            //spanStyle.Setters.Add(new Setter(TextElement.FontSizeProperty, 7.0));

            var materialDesignSourceStyle = (Style)Application.Current.Resources["MaterialDesignWindow"]; //MaterialDesignTextBlock
            var materialDesignSourceStyle2 = (Style)Application.Current.Resources[typeof(MaterialDesignExtensions.Controls.MaterialWindow)];
            // Transfer all properties to spanStyle
            foreach (Setter setter in materialDesignSourceStyle.Setters.Union(materialDesignSourceStyle2.Setters))
                spanStyle.Setters.Add(new Setter(setter.Property, setter.Value));

            foreach (var logEvent in logEvents)
            {
                // Render log message with a template
                var renderedMessage = logEvent.RenderMessage();
                var span = new Span(new Run(renderedMessage));
                span.Style = spanStyle; // Apply the new style to the Span
                if (logEvent.Level == LogEventLevel.Warning)
                    span.Foreground = Brushes.Orange;
                else if (logEvent.Level == LogEventLevel.Error || logEvent.Level == LogEventLevel.Fatal)
                    span.Foreground = Brushes.Red;
                else { } //NTD, will let light/dark mode fontcolor
                lastParagraph.Inlines.Add(span);
                lastParagraph.Inlines.Add(Environment.NewLine);
            }
        }

Any thing I missed?
Feel free to recommend another approach!

Parti dall'esempio di FlowDocumentScrollViewer e ispeziona le risorse esistenti MaterialDesignWindow e MaterialDesignTextBoxBase utilizzate nel metodo di estensione dell'issue. Determina dove deve trovarsi uno stile FlowDocumentScrollViewer e verifica che l'esempio possa fare riferimento a MaterialDesignFlowDocument mantenendo i colori del tema e lo stile del testo previsti.
