E.g. at
https://space.wmflabs.org/2019/08/05/tech-news-2019-week-32/
the text "No Comments" at top is linking to
https://space.wmflabs.org/2019/08/05/tech-news-2019-week-32/#respond
but there's no existing #respond anchor in the HTML, so the page doesn't scroll when we click it.
It does work as expected if there are 1 or more comments, but it uses a different anchor-target (#comments), which might be the problem above. I.e.
https://space.wmflabs.org/2019/07/25/structured-data-on-commons-a-blog-series/
the text "1 Comment" at top is linking to
https://space.wmflabs.org/2019/07/25/structured-data-on-commons-a-blog-series/#comments
Ah, yes, if I hack the URL to use that #comments anchor, then the link works. E.g.
https://space.wmflabs.org/2019/08/05/tech-news-2019-week-32/#comments
