@PuriDilip: Thanks for your interest! Do you have a specific question we can help with? Because I guess that "Run the code locally, find the right place in the code, change code to implement line breaks, test your code changes" is not exactly the answer you expect? :)

@Aklapper Thanks for respond

Actually I've installed mediawiki on my local machine but I've some difficulty to setup pdf render-server. I think some kind of special setting requires in LocalSettings.php file.
Please help me to setup the render-server.

@Aklapper let me know anybody(experienced user) who can help me. I knew people are so busy but little bit help will be good for me.

@PuriDilip: General setup questions are out of scope for this task which is only about long URLs overflowing column width. Please refer to https://www.mediawiki.org/wiki/How_to_become_a_MediaWiki_hacker#Feedback.2C_questions_and_support - thanks!

Proton is not enabled for wikidata.org, see https://github.com/wikimedia/restbase/search?q=v1%2Fpdf.js&unscoped_q=v1%2Fpdf.js

Not sure why, @Pchelolo any thoughts? If it's not supposed to be enabled for Wikidata, we should remove the "Download PDF" link
