| evt | The event instance. |
Executes logic after the callbacks registered on the event target have been executed, unless the event has been marked to prevent its default behaviour. EventBase_1.PreventDefault.
This method is designed to be overriden by subclasses. Use it to implement event handling without
registering callbacks which guarantees precedences of callbacks registered by users of the subclass.
Unlike HandleEventBubbleUp, this method is called after both the callbacks registered
on the element and callbacks registered on its ancestors with TrickleDown.NoTrickleDown.
Use EventInterestAttribute on this method to specify a range of event types that this
method needs to receive. Events that don't fall into the specified types might not be sent to this method.
