Steps to replicate the issue (include links if applicable):

• Mark an unreviewed page as reviewed.
• Open the tag menu in the curation toolbar, select a tag, and click on "add n selected tags".
• Reload the page.

What happens?:

The checkbox to "mark this page as reviewed" in the tag menu is not updated with the new review status. The article is set back to unreviewed.

I first observed this on ForAfrika (log).

What should have happened instead?:

The article should remain reviewed.
