Hello,

I have installed drupal with a subtheme for mayo. Now i try to implement style for ckeditor but it doesn't work :

In /admin/config/content/formats/manage/, I configured the button style and wrote this in the dropdown :

p.opaque-misc-link | test

In my css subtheme :

p.opaque-misc-link {

When i create a new content, i can see my new style named 'test' but i can't apply it.

My configuration :

- Drupal 8.9.7

- Python/2.7.5
