If a post includes URLs that are too long, the URL will be cut off on a mobile device. I don't think this should be a huge priority, web editors can link words instead (e.g. Kelli fixed the issue you see here by linking the WHO site to the text itself instead of pasting the complete URL), however, it is still a bug: https://app.usabilla.com/feedback/item/86f8ebb5921359c12a83f9de302788d89da6796b
