No visible link

Hi,

when editing a page or post, it is not possible to see the links in the texte as they are displayed as the rest of the text.

.mce-content-body a {
color: #333;
}
in file https://www.epices-provence.fr/wp-content/themes/oceanwp/assets/css/gutenberg/gutenberg-editor.min.css?wp-mce-4920-20181217

The page I need help with: [log in to see the link]
