        * page/FrameView.cpp:
        (WebCore::FrameView::updateDragAndDrop):
        Use the passed mouse event, instead of the "current" event.  There is no such thing as
        a "drag event".  Asking for the current event during a drag returns a weird system-
        internal event with an invalid mouse location.
