From Knowit:
Vi sender parameteret locale=nb-no til oembed-endepunktet i h5p.ndla.no og viser fram den iframe-koden vi får tilbake derfra. Her er det altså /oembed hos h5p som ikkje tar hensyn til språkkoden.

From Oliver Tacke:

The language attribute as set in the H5P content's metadata (where it's set based on what language is chosen when creating the content) needs to be set by the H5P-Integration (aka the plugin) where the iframe content is defined.

For instance, the Drupal 7 plugin sets it here (h5p.module · 7.x-1.x · project / h5p · GitLab) together with library/embed.php · 7.x-1.x · project / h5p · GitLab and that's why it's working on H5P.org.
