https://en.wikipedia.org/w/index.php?title=Samsung_Galaxy_A7&oldid=668069510 has a references list section as follows(resulted from a mobile edit, apparently)
<ul about="#mwt6" typeof="mw:Transclusion" id="mwIQ" data-mw="{"parts":["* [http://www.techofy.com/samsung-galaxy-a7-slim-and-metallic Samsung A7 Pros and Cons]\n*",{"template":{"target":{"wt":"Reflist","href":"./Template:Reflist"},"params":{},"i":0}}]}">
<li> <a rel="mw:ExtLink" href="http://www.techofy.com/samsung-galaxy-a7-slim-and-metallic">Samsung A7 Pros and Cons</a></li>
<li><div class="reflist " style=""></div></li>
</ul>CX currently cannot process this kind of mw:Transcusion element with multiple da-mw.parts and just removes it from source. But when we do that, there is no references list to adapt to translation, causing a reference existing without reference list, causing publising failure.
We should do a validation for these cases and remove the references in sections as a fix for now.
