25.4.3 The Promise Constructor
...
The Promise 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 Promise behaviour must include a super call
to the Promise constructor to create and initialize the subclass instance with
the internal state necessary to support the Promise and Promise.prototype
built-in methods.
