[[https://gerrit.wikimedia.org/r/c/mediawiki/extensions/WikibaseMediaInfo/+/604739|Change 604739]] clearly has a `Depends-On` as seen in the commit message:
But it is not shown in the list of related changes as "Depends-On".
The `zuul` plugin adds the needed sections to the DOM. But the section container comes with hidden="true". So `zuul` sections become hidden as well.
We either need to teach the container to flip to visible if zuul has elements, or we make it visible all the time.
(On [[https://gerrit-test.wikimedia.org/r/c/mediawiki/extensions/WikibaseMediaInfo/+/604739|gerrit-test]] the change has open changes on the same topic. So the `Same Topic` section is non-empty, which makes the whole container visible and hence also the `Depends-On` and `Needed-By` sections)
