applet:use last mouse event after dock slide-in

--this way the parabolic effect works nicely after
the dock slides-in. In the past there was a chance
that even though mouse was hovering an parabolicable applet
the parabolic effect was not started because parabolic
event was rejected because the dock was not fully shown
yet
