[api-extractor] APIs defined via module augmentation not included in the report

Is this a feature or a bug?

This could potentially be a bug too

Please describe the actual behavior.

I'm re-exporting a type from another module with module augmentation.

import * as rtdb from '@firebase/database-types';

// Augment the FirebaseDatabase type
declare module '@firebase/database-types' {
  export interface FirebaseDatabase {
    getRules(): Promise<string>;
    getRulesJSON(): Promise<object>;
    setRules(source: string | Buffer | object): Promise<void>;
  }
}

// Re-export the augmented type
export namespace database {
  export import Database = rtdb.FirebaseDatabase;
}

The generated API reports (both the json file and the markdown file) do not mention any of the APIs added via augmentation.

What is the expected behavior?

APIs added via module augmentation should be included in the API report.

If this is a bug, please provide the tool version, Node.js version, and OS.

• Tool: API Extractor
• Tool Version: v7.10.4
• Node Version: v10.22.0
  • Is this a LTS version? Yes
• OS: Mac
