Issue when subclassing a bound function used as constructor

let C be some constructor
let D = C.bind(obj, a, b)
Thanks to the carefully designed `D.[[Construct]]` internal method, the following expressions are equivalent:
new D(...args)
new C(a, b, ...args)
Consider now:
class E extends D {
contructor(...args) {
super(...args)
}
}
As I understand, `super(...args)` calls `D.[[Call]](this, args)`, which in turn calls `C.[[Call]](obj, [a, b, ...args])`. But what we probably want here, is `C.[[Call]](this, [a, b, ...args])`.
I am missing something or is there an issue?
