with the dialog animation in place (which was not a thing in the old
implementation) the action may be triggered before the dialog has finished
the animation (because it is async, e.g. D-Bus call on interface which
involves event loop) and (for example) locking the screen when the dialog
has not dissapeared yet making the animate complete once the screen is
unlocked. to make the transition smooth delaying it by a little is a must
