Steps to Reproduce:
- Open https://en.wikipedia.org/wiki/Special:NewPagesFeed
- Select "New Page Patrol" and sort by "oldest"
- Choose oldest article and click review
- From the article click the arrows to go to the new article in the queue
For old articles this button then greys out. It doesn't seem to effect articles from 2018 and does effect articles from 2008. I don't know where in that range the cut-off is.
Takes you to the next article in the queue.
