Comment (by kittmedia):

 You did all right! I missed some details, sorry for that …

 On a single site installation, it works fine as you also discovered. I can
 reproduce it in a clean multisite installation. To see the Custom CSS in
 the Customizer as “bob” you need to re-map the capability:

 {{{#!php
 <?php
 function map_css_cap( $caps, $cap ) {
         if ( 'edit_css' === $cap && is_multisite() ) {
                 $caps = array( 'import' );
         }
         return $caps;
 }

 add_filter( 'map_meta_cap', 'map_css_cap', 20, 2 );
 }}}

 If you then re-do what you did on the single site installation, it should
 produce the wrong CSS.
