[BUG] Declaration Merging not working/supported

[reey]

Overview of the issue

Declaration Merging is not working.
Not sure if this should be considered as a bug or feature request.
If I e.g. create two interfaces with the same name:

export interface SpecificExtensionKeys {
  test1: string;
}

export interface SpecificExtensionKeys {
  test2: string;
}

I would actually expect something like:

export interface SpecificExtensionKeys {
  test1: string;
  test2: string;
}

To get documented. Instead of that I'm getting the two interfaces separately documented.

This should e.g. also work in case of global namespaces. Using the same global namespace in two locations:

declare global {
  namespace SomeTestNamespace {
    interface SpecificExtensionKeys {
      test1: string;
    }
  }
}

declare global {
  namespace SomeTestNamespace {
    interface SpecificExtensionKeys {
      test2: string;
    }
  }
}

Operating System, Node.js, npm, compodoc version(s)

OS: Windows 10
Node.js: v18.18.2
npm: 9.8.1
compodoc: 1.1.23

Angular configuration, a package.json file in the root folder

does not appy.

Compodoc installed globally or locally ?

locally

If possible sourcecode of the file where it breaks

does not appy.

If possible your terminal logs before the error

does not appy.

Motivation for or Use Case

Allows to define global interfaces across sub entry points. That can also be extended by the library consumer.
