List of steps to reproduce (step by step, including full links if applicable):

• Open page with images;
• Click on image.

What happens?:
File page opens.

What should have happened instead?:
File preview should have opened.

Software version (if not a Wikimedia wiki), browser information, screenshots, other information, etc:

Software version: MediaWiki 1.35.2, PHP 7.4.18, SlimboxThumbs 2014-04-01 (379f277)

Version page URL (archived): Special:Version (archived)

Page URL: https://absurdopedia.wiki/Лунтик

Browser log (developer console) when visiting page with images:

Uncaught ReferenceError: $ is not defined
    <anonymous> https://absurdopedia.wiki/Лунтик:401
Лунтик:401:1

What is really interesting is that when I type $ in developer console after the page was loaded, it does not respond with "$ is not defined" error. I guess, inline script loads before jQuery and therefore fails.
