 '''To reproduce:'''

 Add a Post Type Archive link as a submenu item.

 '''Expected Result:'''

 Parent `$item` object in menu should have `$item->current_item_parent` as
 `true`.

 '''Current Result:''

 `var_dump` of the parent menu's `$item` in the
 `Walker_Nav_Menu->start_el()` shows `current_item_parent` as `false`.

 Interestingly, `$item->menu_item_parent` of the current menu item (the
 post type archive) is set to the correct menu item object ID.

 ---------

 Note, in the past there have been quite a few reports of the Post Type
 Archive link and it's parents not receiving the correct CSS classes. This
 has been fixed, but I wonder if the fix was only a bandaid and missed the
 underlying issue. I'll keep investigating and report back if I can figure
 out a potential solution.
