Let’s say you have the following document structure:
A → B → C → D → E → F → G
d.addEventListener(ev.S,stuff); // ev is (string,true,true)
So… g dispatches ev.S, and reaches d.
Now my question is if it’s necessary to stop propagation or if that function call alone would be more expensive than letting it go all the way up (given that nothing else in the way is awaiting for that particular event)?
Is it completely irrelevant (given a constant use of it)?
