Sorting order of newly created child elements on workspaces is wrong
- IRRE field at a page record
- add new child records in workspace mode
The sorting order of the records is stored incorrectly and will also be mixed up on publishing these new records. The reason for that is, that the sorting order of the placeholder records (which are created for new workspaces elements as a "live pendant") is not updated.
