Testing on ar.wiki
✅ Discussion tools Beta Feature is enabled and the Show metadata about each discussion and enable a new page layout list item appears within it

✅ Verify that all section headings are styled in the way we defined in T310914
✅ Verify that all sections that contain signed comments contain metadata in the way we defined in T310914

✅ Verify that all sections that do NOT contain signed comments do NOT contain any metadata

✅ Verify that the metadata contained within each Topic Container is accurate

✅ Visit a talk page that is NOT in the User or Article talk namespace and verify that Topic Containers do NOT appear.

@matmarex Other Observations:
hu.wiki:

• hu.wiki does not have Show metadata about each discussion and enable a new page layout explicitly listed under Discussion Tools
  
  but cs.wiki and ar.wiki shows it fine
  
• When adding a topic, a different title is displayed on publish. See https://photos.app.goo.gl/P2TEqRqX7qm25rJv7. This p[articular one is tricky because I think Google translate is messing it up. See https://photos.app.goo.gl/etcg4h2HUzwZ7QwG7

I’ve updated the translation yesterday, should be available next week. (If it’s very important, it could in theory be backported, but I’ve never seen translations being backported.)

It’s only Google Translate, nothing’s wrong with DiscussionTools. See wikt:test#Hungarian.

Yes, both of these look as expected to me. Thank you both for checking :)

For a moment I was worried that Google Translate was translating the text that you were writing, which would be bad (at best that just messes up your text, since you're probably not writing in Hungarian while using translation from Hungarian; at worst it might cause the editor to stop working), and which has happened in the past with other translation plugins: T267747: VisualEditor replaces templates with code, adds strange font tags. But it looks like the text you typed was actually saved correctly (see e.g. this diff), and it's just getting translated when shown, which seems normal.
