Steps to reproduce

1. Configure a comboBoxField using optionListDatasource like below:

       selectOne:
         $type: comboBoxField
         defaultValue: internal
         datasource:
           $type: optionListDatasource
           sortable: false
           options:
             - name: disabled
               value: disabled
               label: disabled
             - name: auto
               value: auto
               label: auto
             - name: off
               value: off
               label: off
   

.. Logs, screenshots, gifs...

Expected results

• The combo box entries show up in the defined order (disabled -> auto -> off)

.. Justify non-trivial expectations with a link to a doc or a relevant discussion.

Actual results

• Since Magnolia 6.2.7, entries show up in alphabetical order
• This seems to have been introduced with 6.2.7 / MGNLUI-5994

Workaround

• No.

Development notes

• Documentation update required.
