Drag/Drop position column missing after upgrade

Issue in ./help/merchandising-promotions/visual-merchandiser.md
Our store restricted admins are no longer able to set the position on products in a category via the drag/drop handles. The admins with the catalog responsibility are segregated by store and will not be global admins.

Start with help/merchandising-promotions/visual-merchandiser.md and compare its instructions with the reported drag/drop behavior for store-restricted administrators. Confirm whether the documentation explains how catalog-responsible admins set product positions after the upgrade; done means the file accurately reflects that workflow.
