Confusing cancelBubble

[arv]

The code seems to have some strange behavior related to cancelBubble in the event handlers.

For example if I have two functions listening to the same event on the same target and the first one calls event.stopPropagation() the second one should still be called.

I don't understand what the intent is by checking cancelBubble. Did you mean to check defaultPrevented?

This issue is super old, not sure if relevant anymore.

We haven't actually answered this satisfactorily. It also helps me remember that we have a general issue that our event delegation system is under-designed.

Is this still relevant given that cancelBubble has been deprecated? http://dom.spec.whatwg.org/#event

cancelBubble is no longer relevant. Polymer no longer does event
dispatching, instead putting listeners directly on elements containing
declarative event attributes. The normal methods of affecting event
bubbling should now work: event.preventDefault() and
event.stopPropagation().

Just to be clear preventDefault is unrelated to event propagation (a lot of
people have cargo culted these two into the same bucket)
