Steps to Reproduce:

I apologize if this is not the correct place for this issue, I tried hard finding the repository that is responsible for js intellisense.

1. Create a new js file
2. Copy below code into the file

function Mixin1 (base) {
  return class extends base {
    foo() {}
  }
}

function Mixin2 (base) {
  return class extends base {
    bar() {}
  }
}

class IntermediateDummyClass extends Mixin1(Object) {}

/**
 * @implements {IntermediateDummyClass}
 */
class Composite extends Mixin2(IntermediateDummyClass) {
  
}

let c = new Composite;

c.

3. Observe autocomplete suggestions - within Composite class both foo and bar are suggested

However when instantiated or extended only bar is picked up.

Does this issue occur when all extensions are disabled?: Yes

Empieza ejecutando la reproducción de JavaScript proporcionada en el servicio de lenguaje TypeScript y compara IntelliSense para Composite, su instancia y una clase que hereda de ella. Rastrea cómo se aplica la regla JSDoc @implements en la reproducción y, después, verifica que foo y bar se sugieran de forma coherente para la clase, las instancias y las clases derivadas.
