Component restrictions are not working

Steps to reproduce

1.  Go to our demo (as superuser) and at the Resources app, edit the /mtk/templates/components/html.yaml file
2.  Regarding our docs, include the following snippet

   deletable: false
   writable: false
   moveable: false
   personalizable: false

1. Login as eric and open a pager which has an HTML component within it
2. Check only delete and move are restricted

Expected results

The editor can't edit, create component variants, delete or move the HTML component

Actual results

The editor can edit and create variants on the restricted HTML component

Workaround

The rules are implemented. Just missing in the configuration. Hotfix or decorate the config to add missing rules (not tested).

Development notes

Even including this restrictions on the pages.yaml file, the editor con edit and create variants on the HTML component:

main:
    availableComponents: # using all components from footer plus others
      <<: *footerAvailableComponents
      html:
        id: mtk:components/html
        permissions:
          write:
            roles: 
              superuser: superuser
          delete:
            roles:
              superuser: superuser
          move:
            roles:
              superuser: superuser
          add:
            roles:
              superuser: superuser
          personalize:
            roles: [superuser]
