ESNext+[[Define]]: false positive error accessing parameter property of base class in initializer of derived class

[ajafff]

Code

// @target: esnext
// @useDefineForClassFields. true
class C {
    constructor(public foo: string) {}
}

class D extends C {
    bar = this.foo;
}

Expected behavior:

No error. The constructor of C (and therefore the initialization of foo) is already executed when bar is initialized.

Actual behavior:

used before initialization error on this.foo
