The same as contentHtml because it was derived from contentHtml. But we need to provide a string for contentL3Html. The input has contentL3Html as an entität, but the expects a string. So we should provide the same translated HTML? Actually, the input says contentL3Html is an entität with _deduplicated_text etc., but the expects a string. So we should just provide the translated HTML string for contentL3Html as well. But note: the contentL3Html represents the full article including all layers, but the article has no explicit layering, so we can set it to the same as contentHtml.
