Currently when the summary boxpointer is ungrabbed automatically because the keyboard focus was moved outside the message tray (for instance by selecting the overview search entry or opening the right-click menu of a dash item), after the popup is hidden _updateState() will grab focus and show the popup again. Work around this by unsetting the clicked summary item when losing focus to an actor outside the message tray. https://bugzilla.gnome.org/show_bug.cgi?id=685156
