Change Code Editor UI Colors?

I'm running Animate on Windows 10 and I would like to apply dark mode coloring to Animate's code editor, but it appears I'm unable to customize the colors of the scroll bars and the line numbers area.
It seems those parts of the UI are not customizable through the following menus in Animate:
- File > Preferences > Code Editor > Editing Options > Modify Text Coloring Button
- File > Preferences > Interface > Color Theme > Dark
And it appears this has been a long-lasting issue, as Adobe Animate 2018 has this problem as well.

Nevertheless, I thank you for any other suggestions you may have for fixing this issue. I find it's more comfortable for my eyes to code completely in darkmode, and I wish to be able to do that while I write and test JSFL scripts directly from Animate.
