The menu ui produces a paginated list of menus based on the Drupal\Core\Entity\EntityListBuilder limit property. When parsing the menu set, this pagination is not accounted for, which gives the false impression that the user does not have access to some menus.
Create 50+ menus and configure permissions for a menu that has an ordered weight >50.
Extend the Drupal\menu_ui\MenuListBuilder class and set the "limit" property to false.
This will alter the menu ui for all users, so it would be nice to keep the pagination somehow, but process the entire list of menus.
