Example of working `@extends`?

I have components that extend from a base component. I'd like them to inherit the documentation from the base component but when using `@extends` it doesn't seem to give me the result I'm looking for.

In my base class:
```
/**
* The base component
*
* @class BaseComponent
* @interface BaseComponentArgs
* @export default
* @public
*/
```

In my extended components:
```
/**
* Extended component
*
* @class ExtendedComponent
* @extends BaseComponent
*/
```
