Research direction
Investigate the dark mode implementation in PR #11857, particularly how themes are applied to DropDownButton controls in WinForms. Examine the DemoConsole project files, especially the Designer or UI components where 'Type Here' DropDownButton is rendered. Check if the button's color properties are overridden by the dark mode theme or if there's a missing style application. Refer to the recent dark mode changes in the repository to identify the root cause.
