yes. The chain of EventListeners is determined _before_ the initial dispatch. 
i.e: your
EventListener list is "cloned" at the beginning of the dispatch process.

The ancestor listener won't be called in bubbling phase. Notice that in 
capturing phase
it's the child listener that won't be called.

It's the same. The first method is a generic one from Node and the second
one has a convenient syntax  for the attributes.

Don't  know. Your solution sounds good.

In our implementation, we call Node::removeChild then Node::appendChild.
The events are the ones posted by those 2 methods but I don't know
if it's the solution.
