Event dispatch is divided into three passes, initial, main and final: initial goes from ancestors to descendants and is suitable for scroll containers intercepting events; main is the only pass that goes from descendants to ancestors and is where main logic such as handling clicks takes place; final again goes from ancestors to descendants, letting child nodes know that a parent node consumed part of the event.
