Comment (by wpweaver):

 Looks as if it could be the same issue - from a couple of years ago. I
 didn't find it when I searched.

 But in this case, that issue may have a bit different cause, or have not
 been fixed. After tracking down the NULL item at the failure point, I did
 find such an orphan menu item and removed it which also fixed the issue.

 The issue does seem to originate from defining a menu when a menu item no
 longer exists, or uses a Parent page that no longer exists, and only
 happened when loading the Customizer. Whatever, call to
 `get_post_states()` can pass a null page here. Perhaps the check belongs
 in `get_post_states` as it could be called from other instances, but I
 think it happens only from menu items.
