Change order of field doesn't work

#3268106: [META] Major update for display_fields provides a partial fix for this issue.

1. Adding a field works.
2. Deleting the field works.
3. Moving the field disabled > enabled + save works.
4. Moving the field in Field UI, field groups, etc + save works.
5. Moving the field enabled > disabled + save does not work.

The partial fix fixes the region form widget of the display_fields field which caused a JS error in Field UI. But it did not fix the Moving the field enabled > disabled + save scenario. It looks like the region is not correctly set on the display field config on save.

The workaround is to edit the configuration files and import them.

Example for a field to disable

We need to edit two files, the view display config and the display field configured on this view mode:

root@xyz:/var/www/html/web# ../vendor/bin/drush cim
+------------+-----------------------------------------------------------------+-----------+
| Collection | Config                                                          | Operation |
+------------+-----------------------------------------------------------------+-----------+
|            | display_fields.display_fields_view.taxonomy_term.new_star.modal | Update    |
|            | core.entity_view_display.taxonomy_term.new_star.modal           | Update    |
+------------+-----------------------------------------------------------------+-----------+

In those files, we need to move the display_fields to the hidden section:
