}
What went wrong
click sprite should trigger event
Additional information
If add PickingBehavior::IGNORE to Node , the trigger will fire.
But it's unsound， default node should not block picking。 Other Type such as Button、 Sprite should default block picking。
That might be intentional design. Maybe someone wants to detect clicks on the invisible node. @NthTensor can you weigh in?
I don't have opinions about the default behavior for node. We could add it as a required component, and maybe either ignore or non-blocking make sense.
