FlowDirection="RightToLeft" renders flipped text

[umerfaruk]

Using avalon edit in my WPF application using following snippette

<avalonEdit:TextEditor
                xmlns:avalonEdit="http://icsharpcode.net/sharpdevelop/avalonedit"
                Name="txtFileContent"
                FontFamily="Consolas"
                FontSize="14pt"
                VerticalScrollBarVisibility="Auto" 
                HorizontalScrollBarVisibility="Auto" 
                WordWrap="True" FlowDirection="RightToLeft">
</avalonEdit:TextEditor>

And it renders with text flipped.

Using .net framework 4.7.2 on Windows 10.
