The [idl interface](https://dom.spec.whatwg.org/#interface-customevent) and servo's implementation had diverged. * Extra arguments to initCustomEvent are optional (fixes `dom/events/CustomEvent.html`) * The CustomEvent constructor is infallible * "[Exposed=*]" (and the same for the "Event" interface since it's CustomEvent's parent.)
