Page title does not appear for custom controller with no resource

Title is defined by: https://github.com/thoughtbot/administrate/blob/main/app/views/layouts/administrate/application.html.erb#L22

For custom controllers as described in https://administrate-demo.herokuapp.com/adding_controllers_without_related_model the title of the page is only "- AppName"

Intended behavior: Use the resource name defined in (example): app/dashboards/stat_dashboard.rb
