At the end of the first paragraph there is reference #1. If you scroll to the reference list, it will look empty. Actually, the reference, which can be edited, contains an unnamed link. The markup guide for en.wp says these links are "Only used within article body for footnotes", so it makes sense that VE should display them correctly.
Change 97037 had a related patch set uploaded by Catrope: Also apply autonumbering CSS to links in generated content https://gerrit.wikimedia.org/r/97037
This happened because the numbered link was generated by a template (indirectly in this case: it was in the references list which was in turn generated by {{reflist}}), and the CSS we use to do the numbering didn't account for numbered links in templates.
