I believe this example is not working as reference is shown on hover and not in the margin

where the doc says
> As an example, when I cite Xie, Allaire, and Grolemund ([2018](https://quarto.org/docs/authoring/article-layout.html#ref-xie2018)), the citation bibliography entry itself will now appear in the margin.

Or maybe it is but far away below... in there: https://quarto.org/docs/authoring/article-layout.html#options-reference
