Unpublish paragraph doesn't work correctly in multilangual

Patch #21 works for me

The patch doesn't work for me. I did a workaround via CSS and Twig:

In the paragraph-Template I set the class:

'lang-' ~ paragraph.get('langcode').value

Via CSS I hide the "other" language:

html[lang=en] {
  .paragraph.lang-de {
    display: none !important;
  }
}

Adding more relevant issues from core.

The most promising in my opinion is 🐛 EntityRepository::getTranslationFromContext() function forcibly adds default entity language to fallback candidates Needs review

If an API lands in core for disallowing this kind of fallback we can rely on that add a setting to a field formatter.
