Review comment (refactor):
How about:
```suggestion
        urls = traverse_obj(
            get_elements_html_by_class('iframeContainer', webpage),
            (..., {extract_attributes}, lambda k, v: k == 'data-src' and Art19IE.suitable(v)))

        return self.playlist_from_matches(urls, article_id, ie=Art19IE)
```
That way, we prevent iframes from getting picked up that don't actually contain art19 URLs.
