* Initial plan * Fix taskbar icon disappearing on Win11 when window loses focus Add ShowInTaskbar = true to Activated event handler to ensure the taskbar icon remains visible when the TabWindowView regains focus after being switched to the background by other applications. This complements PR #1028 which fixed the minimize/restore case.
