I don't think this can be right, can it? The `if` and `else` have the same body. These branches used to retuern `index.html` or `${Path}${Ref.Name}.html`. Either the old behavior was correct, or this should be simplified to:

```suggestion
  if (Ref.RefType !== "namespace") {
      Path = `${Path}${Ref.Name}.html`;
```
