After creating a new permission, continue editing from the same point

In UIU-98, we added the ability to specify the permissionName of a brand-new permission. (It's impossible to edit this field after the record has been created – that is enforced on the server side,)

At present, because the permission displayed in the editing area gets reloaded from the WSAPI, the editing starts again from a no-field-focused state. It would be nice if, after the new permission record is created, the continuing editing that happens on the now-existing record automatically resumed from the same field that the administrator was moving into.
