Comment:

 We can do this now easily with setting validation, where the `sanitize`
 method for `WP_Customize_Nav_Menu_Item_Setting` class can return a
 `WP_Error` when the return value of `esc_url_raw()` is empty. This will
 cause the setting to be blocked from being saved and the error message
 will be displayed in the control.
