Wrong membership infering for es6 classes' methods

[NumminorihSF]

Currently there is an issue with inferring membership from es6 class for its method.
Method become a part of globally defined class instead of class that is defined inside own module.
So method the method that is BigFeature.MyClass#method become MyClass#method and documentation is not readable for such cases. To resolve it I should manually write @memberof BigFeature.MyClass for every method.
Expected behavior is proper inferring for such cases to prevent writing extra comments.

• What version of documentation.js are you using?: 8.1.0
• How are you running documentation.js (on the CLI, Node.js API, Grunt, other?): npx documentation build example.js -f md

Input:

/**
 * My big feature.
 *
 * @module BigFeature
 */

/**
 * My class.
 *
 * @memberof BigFeature
 */
class MyClass {
  /** My method */
  method() {
    return {};
  }
}

Current output (for md):

<!-- Generated by documentation.js. Update this documentation by updating the source code. -->

### Table of Contents

-   [BigFeature][1]
    -   [MyClass][2]
-   [method][3]

## BigFeature

### MyClass

## method

[1]: #bigfeature

[2]: #myclass
