New hotfixed instance (in dev mode) leads to display of sw.js

What: the internal JS script sw.js is displayed to users

How to reproduce:

• Take the the Nuxeo ZIP distribution and unjar it

  cd nuxeo-server-10.10-tomcat/bin
  nuxeoctl register # (use a Studio TOKEN)
  nuxeoctl mp-hotfix --accept=true
  nuxeoctl mp-install nuxeo-web-ui nuxeo-jsf-ui --accept=true
  nuxeoctl console
  

• invoke http://localhost:8080
• fill in the wizard information: all default (including Dev mode) but no need to install any other package
• reboot from the GUI and wait for login page
• login as Administrator/Administrator
  => The resulting URL looks like: http://localhost:8080/nuxeo/ui/sw.js?ts=1605452580213
  => the page looks like

  importScripts('workbox/workbox-sw.js');
  workbox.loadModule('workbox-strategies');
  
  const params = new URL(self.location.href).searchParams;
  if (params.has('ts')) {
    workbox.routing.registerRoute(
      ({ url, event }) => /\.*\.(html|js)$/.test(url) && event.request.headers.get('Content-Type') !== 'application/json',
      async ({ url, event }) => {
        const strategy = workbox.strategies.networkFirst();
        const request = new Request(`${url}?ts=${params.get('ts')}`, { credentials: 'same-origin' });
        return await strategy.makeRequest({ event, request });
      });
  }
  
  self.addEventListener('install', () => {
    self.skipWaiting();
  });
  

Expected result: sw.js should never get displayed.
