"nojs" mode does not handle properly the ZIM with multiple languages

See, this screenshot:

Not sure exactly how it should be fixed, but it should not be that ugly like now

Root Cause

Q: Why do we see this issue?
We see this issue when observing the Kiwix Library by leveraging the link: https://library.kiwix.org/nojs.

Q: Why do we see language tags when we hit the link: https://library.kiwix.org/nojs?
The answer lies in the TED talk books: https://library.kiwix.org/nojs?lang=&category=&q=ted. If you visit this link, you will see the response in the Chrome tab:

Here, we can see that the

element with the CSS class book__languageTag contains multiple languages delimited by commas instead of a single language (e.g., eng, swa, or ces). Ideally, it should be a single language for each book tile.

Potential Fix

I am unable to access the zim file XML library, but my hypothesis is that the issue lies in the XML data for the TED books. If I could get access to this library, I would be able to investigate further and address this problem.

Questions

Q: I went through the documentation: kiwix-serve. My understanding is:

• When we start the daemon using kiwix-serve, the --library option provides a directory that contains all the books available on the Kiwix Library website.
• Somewhere in the XML files, we should have the data for the TED books as well. If we can fix that, it should resolve this issue.
• Another option would be handle in the code, I believe code generates the HTML, so, here we need to ensure that langCode isn't comma separated list, but rather it should be a single language.

Please confirm if my understanding is correct and guide me on how to proceed with accessing the XML library to verify and address this issue.
