If a user/role (other than uid 1) don't have the permission 'show administration menu in the toolbar', nested menus do not work.
The top level is rendered, but sub levels are not visible.
@see: https://www.drupal.org/project/toolbar_menu/issues/2949053#comment-12681327 →
As suggested in this issue → for the toolbar_menu module, change the line 36 in toolbar_menu_clean.module file :
unset($items['administration'])
by
$items['administration']['#wrapper_attributes']['class'] = 'visually-hidden';
I discover the toolbar_menu_clean project from this issue → on toolbar_menu project. Clearly, toolbar_menu_clean is an important complement to toolbar_menu to provide a good "editor" or "webmaster" experience ! IMHO, 2 project are related and thing will be easier if it was only one project (maybe with a submodule).
