If a window is hidden remove it from the S&T group. This happens when MediaPlayer goes fullscreen. Maybe not optimal but at least consistent with terminal which also left the S&T group in fullscreen mode. This is because the terminal has no decorator in fullscreen mode and thus can't be stacked any more (maybe this should be solved in the future...). Fixes #7895, #7896.
