Comment:

 Attached is a patch that will

 - ensure that the current category has a parent category,
 - ensure that the category permastructure actually contains the category
 slug `%category%`

 Only then it will

 - generate a list of all parent categories,
 - check if the category path matches the
 `$wp->query_vars['category_name']`
 - replace the incorrect category path `$wp->query_vars['category_name']`
 with the correct one

 Notice that this approach will respect any pagination, feeds and custom
 endpoints that might be present in the URL.
