Prevent PathView's parent stealing mouse grab during double-flick

This commit fixes an issue where mouse events could be stolen by the
parent of a PathView due to the PathView not correctly setting the
keep-mouse-grab flag in handleMousePressEvent().  This commit ensures
that the flag is correctly set, so that the second flick in a double
flick is handled by the PathView rather than being stolen by the
parent.
