CPT archive with pagination does not set current-menu-parent and current-menu-item after flip

[beelde]

1. Create child theme of one of the wordpress themes (e.g. twentyfifteen).
2. Add following example code to your functions.php:

   add_action( 'wp_enqueue_scripts', 'enqueue_parent_theme_style' );
   function enqueue_parent_theme_style() {
       wp_enqueue_style( 'parent-style', get_template_directory_uri().'/style.css' );
   }
   
   register_post_type( 'Products',
   		
   	array(
   
   		'labels' => array(
   			'name' => __( 'Products' ),
   			'singular_name' => __( 'Product' )
   		),
   		'public' 		=> true,
   		'has_archive' 	=> true,
   		'supports' 		=> array('title', 'thumbnail', 'author'),
   		'menu_icon'	    => 'dashicons-book-alt',
   		'rewrite'		=> true
   	)
   );
   

3. Add 4 products
4. Set "Blog pages show at most" to 3
5. Add custom link to CPT archive "/products/" to menu (Pretty Permalinks pls)
6. Go to the archive page and flip to second page.

Excepting that this should work without a lot of dark workarounds.

Hi beelde - Thanks for the report. The reason why the current-menu-item logic is not working is because the menu item you are adding is a simple link - ​http://example.com/products/ - and from WP's point of view, ​http://example.com/products/page/2 is not the same thing as ​http://example.com/products.

The most natural way for this to work would be for WP to introduce native support for menu items that link to post type archives. See #16075.
