Open the Adaptive Cards URL and reproduce the issue in Windows 11 high contrast mode, following the Designer and “create a new card” paths described in the report. Inspect the Test Editor area, expanded control icon, and close button; done means these controls and the text-edit area visibly adapt to high contrast settings.
