We are not reliably inserting a space between the backlinks and the reference content in the references section:
echo '<ref name=foo>a</ref><ref name=foo/><references/>' | node parse --extensions ref,references
<body><span about="#mwt4" class="reference" data-mw='{"name":"ref","body":{"html":"a"},"attrs":{"name":"foo"}}' id="cite_ref-foo-1-0" rel="dc:references" typeof="mw:Extension/ref" data-parsoid='{"src":"<ref name=foo>a</ref>","dsr":[0,21,14,6]}'><a href="#cite_note-foo-1">[1]</a></span><span about="#mwt5" class="reference" data-mw='{"name":"ref","attrs":{"name":"foo"}}' id="cite_ref-foo-1-1" rel="dc:references" typeof="mw:Extension/ref" data-parsoid='{"src":"<ref name=foo/>","dsr":[21,36,15,0]}'><a href="#cite_note-foo-1">[1]</a></span><ol about="#mwt6" class="references" data-mw='{"name":"references","attrs":{}}' typeof="mw:Extension/references" data-parsoid='{"tsr":[36,49],"selfClose":true,"src":"<references/>","dsr":[36,49,13,0]}'><li about="#cite_note-foo-1" id="cite_note-foo-1"><span rel="mw:referencedBy">↑ <a href="#cite_ref-foo-1-0">1.0</a> <a href="#cite_ref-foo-1-1">1.1</a></span><span>a</span></li></ol>
</body>
Note the missing space in <a href="#cite_ref-foo-1-1">1.1</a></span><span>a</span>
Should probably be: <a href="#cite_ref-foo-1-1">1.1</a></span> <span>a</span>
