CPTs are not showing by default on Appearances > Menus page

[mehul0810]

I have noticed that with fresh WP instance adding CPTs using register_post_type and setting public to true doesn't show that CPT on Appearances > Menus page.
Also, found that the CPT created is listed under metaboxhidden_nav-menus from function ​https://github.com/WordPress/WordPress/blob/master/wp-admin/includes/nav-menu.php#L163

However, It should work with public set to true or show_in_nav_menus set to true. But its not showing when fresh install or Screen Options not set.

Alternative Suggestion: We can overcome this issue by adding a filter here ​https://github.com/WordPress/WordPress/blob/master/wp-admin/includes/nav-menu.php#L169

I agree that a public post type with show_in_nav_menus set to true should be visible in the Menus screen by default. This would be consistent with the visibility of post types in the Customizer's menu editor.
