研究方向
Examine the dark mode implementation in PR #11857 (dotnet/winforms/pull/11857). Focus on how ListViewGroup, Subtitle, and TaskLink colors are set. Investigate the rendering code for these elements, likely in ListView.cs or related files. Check if the dark theme colors are properly applied to subtitles and task links. The issue includes screenshots showing poor visibility; compare with light mode behavior. Comments in the issue may provide additional clues.
