Implemented separately from the other errors because it is defined in terms of WebIDL, where members of an interface are getters on their prototype. See the difference between `JSON.stringify(Object.getOwnPropertyDescriptors(new TypeError()))` vs `JSON.stringify(Object.getOwnPropertyDescriptors(new DOMException()))`. Note: the standard doesn't specify where to put "stack". We follow existing practice which imitates node instead of browsers.
