This issue is similar to other cases of Content Translation substituting a reference template with HTML and wiki syntax instead of adapting it to a proper template, but @Pginer-WMF asked to report it separately anyway. If this is not really a distinct issue, feel free to merge it without asking me.
Here is a relatively easy example that I found: A translation of Twyla Tharp into Hebrew. The original revision has this reference:
<ref name=Kourlas2>
{{cite news
| last = Kourlas
| first = Gia
| title = Twyla Tharp's 50 Years of Forward Movement
| newspaper = The New York Times
| date = 4 April 2015
| url = https://www.nytimes.com/2015/04/05/arts/dance/twyla-tharps-50-years-of-forward-movement.html?ref=dance&_r=0
| accessdate = 6 April 2015
| quote =
}}</ref>It was adapted to this:
<ref name="Kourlas2"> <cite class="citation news">Kourlas, Gia (4 April 2015). [https://www.nytimes.com/2015/04/05/arts/dance/twyla-tharps-50-years-of-forward-movement.html?ref=dance&_r=0 "Twyla Tharp's 50 Years of Forward Movement"]. ''The New York Times''<span class="reference-accessdate">. Retrieved <span class="nowrap">6 April</span> 2015</span>.</cite><templatestyles src="Module:Citation/CS1/styles.css"></templatestyles></ref>
I'd expect it to be adapted to something with {{cite news}}, because there is a corresponding template in the Hebrew Wikipedia.
In particular, notice that the blob in the output has a <templatestyles> tag, which really has nothing to do in an article, and should only be used in templates. This is how I noticed this issue: The Hebrew Wikipedia has an Abuse Filter that doesn't allow new users to use this tag in articles.
There are several other examples, including at least one that is currently in progress and cannot be published because of the AbuseFilter.
