23.3.1 The WeakMap Constructor
...
The WeakMap constructor is designed to be subclassable. It may be used as the
value in an extends clause of a class definition. Subclass constructors that
intend to inherit the specified WeakMap behaviour must include a super call to
the WeakMap constructor to create and initialize the subclass instance with
the internal state necessary to support the WeakMap.prototype built-in
methods.
