Is this code used by cros too?  If not, maybe don't need the "On Desktop" part
of the comment.  Otherwise, is there a check missing for cros?

This is also called from
chrome/browser/ui/webui/chromeos/login/signin_screen_handler.cc
the ".shadow" is really only used in desktop user manager. but I added a check
to be safe.

+      $('login-header-bar').classList.toggle('shadow', users.length > 8);
