As far as practical debugging, browsers should at least issue a warning when code calls `event.stopPropagation()` or other dispatch-changing methods on a "stale" event that has already been fully dispatched. There's already such advice in the spec for `passive` but really it would be better for that term to have been reserved for an event that affects neither the default action *nor* propagation. In that sense, today's `passive` is more like "passive aggressive". 😸 I wonder if there's any benefit of having an `EventOptions` flag indicating full passivity.
