Word breaks in comments


I have noticed that all comments on my site have breaks in the middle of words for some reason.  My Drupal site is up-to-date (8.6.10) and I’m not running any modules to modify the appearance of the comments.  See comments on this page for example.

Can anybody tell me why this is happening and how to resolve?
