Looses preferences UI after you switch from full screen preview of a theme

Description

That is if you e.g. alt-tab instead of click on "Leave Fullscreen". The xfce4-screensaver-preferences and the theme continue to run on background, so you have to kill them manually. I expect to be able to alt-tab back to the screensaver and quit it from UI.
