panelview: Take focus from other Plasma windows when clicked
PanelView is a special case of a window, it is clickable, but it doesn't take focus.
If we're interacting with other plasma components and a user clicks the panel we still want focus to be drawn from those other components. This patch makes PanelView fake focus out events. PanelView still does not take focus, but any windows that close on focus out will work appropriately.
BUG: 367815 FIXED-IN: 6.1
This was tried before and reverted. New version only acts if the mouse event is not handled by the scene.
Requires plasma-desktop!2092 (merged) to be useful
