When 'open in work area' in includes tab, entities are sorted in another order, why?

This article explains entities are sorted in work areas. 

Sorting entities in work areas

In inriver Enrich >Entity Overview > Includes or Included in, you can order linked entities, for example Resources, by drag'n drop. Each link will get a sort order index.

When you open the entities by using Open in work area, they are ordered by the internal system ID (SysID), which is basically when the entity was created.

1. Open in work area ordered by SysID 
   
   
2. Includes / Included in ordered by link index

We currently don't have manual sort order or support the order of link indexes in a work area.
