I encountered the same issue with Twitter auto-inserting unwanted hyperlinks to domains like .app:<p><a href="https://tinyapps.org/blog/misc/201810230715_twitter_disable_auto_links.html" rel="nofollow">https://tinyapps.org/blog/misc/201810230715_twitter_disable_...</a><p>Workaround was to use zero-width space:<p><a href="https://www.labnol.org/internet/twitter-auto-converts-links/20771/" rel="nofollow">https://www.labnol.org/internet/twitter-auto-converts-links/...</a>
