Tabs don't work for show due to scoping to formtastic

Cause:

activeadmin_materialize_theme/app/assets/javascripts/activeadmin_materialize_theme.js

Lines 62 to 68 in 3fec02b

	function initTabs() {
	document.querySelectorAll('body.active_admin .formtastic >.tabs').forEach(
	(el) => el.classList.remove('tabs')
	)
	addClassToElements('body.active_admin .formtastic .nav-tabs', 'tabs')
	addClassToElements('body.active_admin .formtastic .nav-tabs >li', 'tab')
	}

Workaround:

show do
  div class: 'formtastic' do 
    tabs do
      tab do 
        # ...
      end
    end
  end
end
