AEM forms not translating when embedded using <article>

(Reposted in Forms)

AEM Forms 6.5. (Windows)

Using HTL with:

<p data-sly-test="${request.requestParameterMap['section'][0].toString == 'test'}">
<article data-sly-resource="/content/forms/af/myForm/test"></article>
</p>

When the HTL page passes afAcceptLang=fr the contained form "test" doesn't translate. It does translate on its own using afAcceptLang=fr.

Any ideas?
