You can simply test with tugboat (see above).

Thank you, for adding this one. I didn't had time to debug that issue quite well,but it seems that some twig templates suppress adding of the rel attribute. In my case it was https://www.drupal.org/project/ui_suite_dsfr → . So I am happy, to say, that this is not an issue with Drupal CMS. But none the less it's good to have this option in case there is some mess in a theme.

Thanks again for adding that issue here.
