https://github.com/jenkinsci/jenkins/pull/10245 switched "Manage Jenkins » System" from breadcrumb-config-outline to breadcrumb.

As a result, there's no longer a navigation in this config form. As it's often complex to navigate, having no way to jump to sections is a problem.

Job configs address this through the sidepanel, this form does not.
