In Drupal 7 I have the WYSIWYG module installed which provides a configuration setting "Enable on summary fields" to allow the HTML editor to be used on summary fields.
The WYSIWYG module is not available on Drupal 9. Is there a way to configure Drupal 9 to use an HTML editor (CKEditor or something else) to edit summary fields?
I have searched for solutions and I don't want to create a new, separate "summary" field. Drupal already has a summary field that I am already using.
