bug: single-export-module is missing types for defineCustomElement functions

[weaintplastic]

Prerequisites

• I have read the Contributing Guidelines.
• I agree to follow the Code of Conduct.
• I have searched for existing issues that already report this problem, without success.

Stencil Version

3.0.1

Current Behavior

When using the dist-custom-element output target with customElementsExportBehavior: 'single-export-module' we are experiencing missing type declarations for the defineCustomElement... functions of our components.

export { MyComponent as MyComponent } from '../types/components/my-component/my-component';

Expected Behavior

When publishing as a component library, I'd expect that consumers can access the type for the defineCustomElement... function the same way they can access the component's type.

export { MyComponent as MyComponent, defineCustomElement as defineCustomElementMyComponent  } from '../types/components/my-component/my-component';

Hey @weaintplastic 👋

Took a look at this and can confirm there appears to be an issue with how/where the component type declarations are getting re-exported. I'll get this labeled and ingested into our backlog for us to resolve. Thanks for reporting!
