It seems that an earlier check I did to see if events are copied wasn't done
correctly. Indeed events are copied at every filter/handler. That does seem
excessive. It also makes the public `Node#fireEvent` a bit useless for proper
event propagation for normal users that don't have access to `EventUtil`.
I checked the events that are copied, and it is basically making the copy to
adjust the source (target remains constant). That's really odd; I'd expect the
source to remain the same as well (ie. the Scene or Window, not the "previous"
filter/handler Node level), especially as it is documented as:
/**
* The object on which the Event initially occurred.
*
* @return the object on which the Event initially occurred
*/
public Object getSource() {
return source;
}
