leadingComments of anonymous class export are broken.

[h13i32maru]

Hi! I use Espree in ESDoc.

A leadingComments position are unexpected, when I parse following code with Espree.

/**
 * this is anonymous class.
 */
export default class {
  /**
   * this is method1.
   */
  method1(){
  }
}

(full JSON https://gist.github.com/h13i32maru/f22536ca8c224e08cc9e)

Espree option:

  {
      comments: true,
      attachComment: true,
      loc: true,
      ecmaFeatures: {
        arrowFunctions: true,
        blockBindings: true,
        destructuring: true,
        regexYFlag: true,
        regexUFlag: true,
        templateStrings: true,
        binaryLiterals: true,
        octalLiterals: true,
        unicodeCodePointEscapes: true,
        defaultParams: true,
        restParams: true,
        forOf: true,
        objectLiteralComputedProperties: true,
        objectLiteralShorthandMethods: true,
        objectLiteralShorthandProperties: true,
        objectLiteralDuplicateProperties: true,
        generators: true,
        spread: true,
        classes: true,
        modules: true,
        jsx: true,
        globalReturn: true
      }
  };

Thank you.

Can you explain what's wrong? I can't tell from your screenshot.

[h13i32maru]

Sorry, I explain it.

this is anonymous class. is commented on export default class, but the comment is inserted into leadingComments of method1().

Is this would be the correct behavior?
I expect that the comment is inserted into leadingComments of ExportDefaultDeclaration.

Thanks for explaining. Yeah, that looks like a bug to me.
