After updating vaadin version to 24.3.5 vaadin for some reason saves to the cache a request to an internal resource instead of the page visited by an anonymous user. So after authorization user sees vaadinPush.js file.
In this case we use vaadin.url-mapping and this request to the resource goes without url-mapping.
In fact, I don't even know where to start digging through the source code to override the class or method that calls this save.
Expected behavior: vaadin saves the request only to the page and not to internal resources
Same issue as #13190
