When you disable `Show accent color on title bars and window borders`, the hover background color of the caption button is inconsistent to UWP in dark mode. (Light mode is Ok)

Research direction

Start by reproducing the issue in WinUI 3 with Windows App SDK 1.6.5 on Windows 11 24H2 while accent colors are disabled, then compare the dark-mode caption-button hover behavior with UWP. Done means the minimize, restore, and maximize hover background colors match UWP.
