When a field has some third-party settings - they passed well to the render array if the module has the value.
But if the value is empty, they get lost, preventing the expected rendering logic from working.
1. Configure some third-party settings in the field display settings, for example, create a text field and using this module
https://www.drupal.org/project/fences →
add a class "foo" to it.
2. Render the field with the filled value and see that the class is present.
3. Configure the Empty value behavior to display a custom text, and make the real field value empty.
4. See that the class becomes missing in the rendered HTML.
Read the third_party_settings from the field formatter and apply them to the field.

I fixed this issue in the MR https://git.drupalcode.org/project/empty_fields/-/merge_requests/8 - please review.
Attaching a static patch file with those changes, to make it possible to use in composer until 🐛 GitLab Merge Requests Unable to Generate Incremental Patch Files Active is resolved.
