In the LightweightDispatcher we (usually) dispatch MOUSE_RELEASE events
to the same target as the corresponding MOUSE_PRESSED event. This is ok,
but only as long as this component is still there. If it's made
invisible for some reason, we need to dispatch the mouse event to the
component that we found.

* java/awt/LightweightDispatcher.java
(handleMouseEvent): Dispatch event to real target if
the dragTarget has become invisible in the meantime.
