Reproduce the problem

• keep the console open

• see that you get a JS error in the console: Uncaught ReferenceError: duplicatePostNotices is not defined
• edit the post
• click on "Ripubblica" ("Republish"), also in the pre-publish confirmation sidebar
• see that you are not redirected to the republished post but you stay in the same screen and you get a notification telling that the draft has been saved
• navigate to the post list and see that the republishing actually happened anyway
