(XUL popuphiding is cancelable, but I couldn't find any case where the event is actually cancelled in FF code.) I'm ok leaving hide as non-cancelable. I think it has fewer...

I'd be ok having implicit "this" capture only when one is within the same algorithm basically. But if for example in that example, 2.1 was a link to an algorithm...

I and @petervanderbeken happened to discuss about this and also prefer option 2 of those three options (and the way Firefox stores srcdoc). Should be relatively easy to implement and...

The current window.open() does indeed have a quite a few odd quirks, so perhaps a new API would be reasonable. But before adding anything it would be good to figure...

It would help implementers (at least Mozilla) if there were a bit more concrete proposal here. It sounds like the use cases require effectively a DOM node tree, without the...

I don't understand the comments about mixing bubbles and EventTarget. Bubbling is a property of the Event, not EventTarget (and it just tell that the event dispatch does only capturing...

Why would we disable stopImmediatePropagation or stopPropagation. I don't see any strong reasons for that. About listeners only for trusted events, Gecko has had wantsTrusted option / 4th param for...

> `giveSignalToSomeone()` could prevent `userlandFetch()` from seeing the signal was aborted by using `stopImmediatePropagation()`. ...if using event, and that is the whole point of stop*propagation. The same applies to all...

Gecko would implement this or some variant of it. (which isn't super surprising since looks like I filed https://github.com/whatwg/dom/issues/398 )

Gecko has "system event group", which can be used to implement default handling (as an example) using event listeners. Listeners in that group are called after the listeners in the...
