jQuery transition not run on anon page
I have figured it out, by just adding a bunch of jquery dependencies in my 


  theme.libraries.yml


   js:
      js/leadership.js: {}
   dependencies:
    - core/jquery
    - core/jquery.once
    - core/jquery.ui
    - core/jquery.ui.widget
    - core/jquery.ui.draggable
    - core/jquery.ui.mouse
    - core/jquery.ui.position
    - core/jquery.ui.resizable


once of the jquery ui was missing.
