Re: [whatwg/dom] Allow an EventTarget to provide the default value of the AddEventListenerOptions (#365)

I've opened a PR with the tests @domenic outlined above in https://github.com/web-platform-tests/wpt/pull/34464

Since the tests fail in Firefox and Safari due to test infrastructure issues, I also wrote demos to be able to assess interop. See https://github.com/web-platform-tests/wpt/pull/34464#issuecomment-1157474824

The behavior of both Chrome and Safari for the third demo can't be explained by the existing intervention design docs, as far as I can tell. The behavior seems to be something like: first fire a cancelable event, and if that event is not `preventDefault()`ed, subsequent events for the same gesture are *not* cancelable.
