 /wp-includes/script-loader.php#L2631 the style string is split every 128
 characters. However, it can result in some edge cases that it leave
 dangling comma that would break load-styles.php

 For example, in my sites

 {{{#!php
 php > $s='dashicons,admin-bar,common,forms,admin-menu,dashboard,list-
 tables,edit,revisions,media,themes,about,nav-menus,wp-pointer,widgets
 ,site-icon,l10n,buttons,wp-auth-check';
 php > print_r(str_split($s,128));
 Array
 (
     [0] => dashicons,admin-bar,common,forms,admin-menu,dashboard,list-
 tables,edit,revisions,media,themes,about,nav-menus,wp-pointer,widgets
     [1] => ,site-icon,l10n,buttons,wp-auth-check
 )
 }}}
