[BUG] `mount` is ignored when used in modules

Information

• Version: >=5.5x
• Packages: di

I use modules to avoid duplicating common components. It works well when we speak about middleware, filters, and pipes. However, controllers are just ignored. See example below:

@Controller('/')
export class HealthController {
  @Get()
  @Get('/health')
  @Returns(204)
  public health(): void {
    // noop
  }
}

@Module({
  mount: {
    '/api/v1/': [HealthController]
  }
})
export class HealthModule {
  // ...
}

@Configuration({
  // ...
  mount: {
    '/api/v1/': [ /* other controllers */ ]
  },
  imports: [HealthModule]
})
export class Service {

}

I have tried to add controllers on the $beforeInit hook, it also has no effect.

@Module({
  deps: [Configuration]
})
export class HealthModule {
 constructor(private readonly configuration: Configuration) {}
 
  public $beforeInit(): void {
    const endpoint = '/api/v1/';

    this.configuration.mount[endpoint] = (
      this.configuration.mount[endpoint] ?? []
    ).concat(HealthController);
  }
}

It seems it somehow connected with importProviders. That method resolves all providers concurrently, while imports must be initialized before building the module itself according to docs.

For me it’s works with the latest version (6.x): https://github.com/tsedio/tsed-example-modules
