Importing Author Fieldset breaks Permissions

Bug description

I have encountered a weird thing with Roles and Author. I have made a description on this Discussion thread.

Basically, if an Author Field is imported alone as a Field, it works. But if the entire Fieldset is imported, it breaks something in the Permissions, and an User can not create or edit Entries, unless he has the complete list of Permission over a Collection.

# Fielset: enseignant_responsable.yaml
title: "Enseignant responsable"
fields:
  -
    handle: author
    field:
      max_items: 1
      mode: select
      display: 'Enseignant·e responsable de ce rapport'
      type: users
      icon: users
      default: current

❌

 # Blueprint experimentation.yaml
  sidebar:
    display: Sidebar
    sections:
      -
        fields:
          -
            import: enseignant_responsable

✅

 # Blueprint experimentation.yaml
  sidebar:
    display: Sidebar
    sections:
      -
        fields:
          -
            handle: author
            field:
              max_items: 1
              mode: select
              display: 'Enseignant·e responsable de ce rapport'
              type: users
              default: current

✅

 # Blueprint experimentation.yaml
  sidebar:
    display: Sidebar
    sections:
      -
        fields:
          -
            handle: enseignant
            field: enseignant_responsable.author

How to reproduce

Create a Role that does not allow to edit other's authors Entries:

 # roles.yaml
prof-experimentation:
  title: 'Prof Expérimentation'
  permissions:
    - 'view experimentation entries'
    - 'edit experimentation entries'
    - 'create experimentation entries'
    - 'delete experimentation entries'
    - 'publish experimentation entries'
    - 'reorder experimentation entries'

Create a Fieldset:

# Fielset: enseignant_responsable.yaml
title: "Enseignant responsable"
fields:
  -
    handle: author
    field:
      max_items: 1
      mode: select
      display: 'Enseignant·e responsable de ce rapport'
      type: users
      default: current

Import it in a Collection Blueprint: import: enseignant_responsable
Try to create a new Entry. At this point, it should display an Undefined array key "author" error.
(Weird side-effect: Add - 'edit other authors experimentation entries' to the role, and it works…). Remove and go to point 6

Import the Field only, It should work:

fields:
-
 handle: my_content_field
 field: enseignant_responsable.author
