Unused citations show up in bibliography (regression?)

[phiresky]

Explain the problem.
In older versions of pandoc, unused citations did not get added to the bibliography. As of some version (I'd guess 2.11), they do.

Example markdown:

---
{"references": [{
    "id": "foo",
    "issued": {
      "date-parts": [
        [
          2018
        ]
      ]
    },
    "page": "1-12",
    "title": "Testing",
    "type": "article-journal"
  }
]}
---


there shouldn't be any references below:

pandoc 2.3

$ pandoc-2.3/bin/pandoc test.md -F pandoc-2.3/bin/pandoc-citeproc
<p>there shouldn’t be any references below:</p>

pandoc 2.14

$ pandoc test.md --citeproc
<p>there shouldn’t be any references below:</p>
<div id="refs" class="references csl-bib-body hanging-indent" role="doc-bibliography">
<div id="ref-foo" class="csl-entry" role="doc-biblioentry">
<span>“Testing.”</span> 2018, 1–12.
</div>
</div>

I'm assuming this is unintended since

1. I can't find anything about it in this changelog: https://github.com/jgm/pandoc/releases/tag/2.11
2. There is no mention of how to toggle this in the manual
3. There is a section specifically about adding unused citations to the bibliography in the manual: https://pandoc.org/MANUAL.html#including-uncited-items-in-the-bibliography

I'm opening this because of phiresky/pandoc-url2cite#8. I also might have missed some info about this somewhere?

Check the changelog for the latest release, 2.14.0.2!

Always good to check closed issues: #7376.

Thanks. I searched for "unused" "unreferenced" and citations issues but somehow didn't see that one. Sorry for the inconvenience
