Wpf edit Scroll bar style

Hi,I have a question about scroll bar style。
I set the Wpf Editor Color Themes style to Dark, but the scroll bar style is still white, which is very ugly. How to set the scroll bar s

tyle to Dark mode,thanks!

We tried to reproduce the problem with light scrollbars when switching to Dark visual theme, but with no success, it seems to work correctly both with version 6 and 7.

Here’s a screen showing how it looks in our CodeEditor (WPF) demo when switching to the dark theme.

Would it be possible to send me (andrew.medevedev@alternetsoft.com) a cut-down version of your project where the problem can be seen?

thanks,This is an old project, the version is 5.1, I need to update to solve it!
