19.5.6.1 NativeError Constructors
...
Each NativeError constructor is designed to be subclassable. It may be used as
the value of an extends clause of a class definition. Subclass constructors
that intend to inherit the specified NativeError behaviour must include a
super call to the NativeError constructor to create and initialize subclass
instances with a [[ErrorData]] internal slot.
