[NuGet][0.10.12.2] How force scrolling to the last line (end of document)

[maxt17]

Hi!
I am trying to use AvaloniaEdit 0.10.12.2 NuGet in one my Avalonia project. I choose TextEditor control to display logs from application. I am able to display log message but I have a problem with scrolling to the end of document (the last line). I tried to used ScrollToLine method but do not work.

 _textEditor.AppendText(Environment.NewLine + item.RenderedMessage);
 _textEditor.ScrollToLine(_textEditor.LineCount);

I checked VerticalOffset property and it is equal 0 after the action. When I scroll by mouse the value changes.
I also tried to put this line to AvaloniaEdit master project, but also without any result.

Could You advice me how I should implement code to get above described scrolling effect?
