Future-dated top-level pages are not automatically added to custom menus

[jamocreations]

I've found that future-dated top-level pages are not automatically added to custom menus, despite my setting to do so.

When a future-dated page is published, the new menu item is added to the 'posts' table (a new row with 'post_type' = 'nav_menu_item'). However, the new menu item is not added to the 'wp_term_relationships' table. In short, the menu item is not saved correctly, and hence does not show up in the custom menu.

Steps to reproduce this bug:

• Activate a theme with support for custom menus.
• Under "Appearance" > "Menus", enable the option "Automatically add new top-level pages"
• Create a new top-level page, and schedule it to be published in the future.
• Wait for the page to be automatically published.
