Node::preDispatchEventHandler and Node::postDispatchEventHandler are only implemented by HTMLInputElement and HTMLMediaElement for a couple of events.
There is no reason every single event dispatch has to pay the cost of calling these virtual functions.

Furthermore, preDispatchEventHandlerResult that's passed around from preDispatchEventHandler and postDispatchEventHandler is only used by HTMLInputElement's preDispatchEventHandler and it's always of type ClickHandlingState. Since ClickHandlingState is never subclassed, we don't even need to heap-allocate this object.
