Customizer and param show_in_nav_menus and custom posts or taxonomies

New with WordPress 4.3:
When registering new taxonomy or new post !

If you don’t want unexpected new item in the new Menu Customizer, param show_in_nav_menus must be set to false !
The new items list appears in the second column of the Theme Customizer when a menu is selected !
Param show_ui set to false is not enough !
