Service Worker Terdaftar dan Diaktifkan tetapi Tidak Bekerja dalam Mode Offline

Dalam aplikasi UI5, saya telah mendaftarkan pekerja layanan saya di index.html:

$(document).ready(function() {
  if ('serviceWorker' in navigator) {
    navigator.serviceWorker
      .register('service-worker.js', { scope: './' })
      .then(function(registration) {
        console.log("Service Worker Registered");
      })
      .catch(function(err) {
        console.log("Service Worker Failed to Register", err);
      })
  }
});

Selain itu, saya memiliki file service-worker.js di folder root sehingga pekerja layanan dapat menyimpan semua elemen di bawahnya dalam cache. File ini berisi kode berikut:

// Set a name for the current cache
var cacheName = 'v2'; 

// Default files to always cache
var cacheFiles = [

Dengan semua ini, pekerja layanan saya terinstal dan diaktifkan dengan benar. Dan jika saya membuka tab Penyimpanan Cache, saya memiliki informasi yang di-cache:

Koneksi saya aman (HTTPS) tetapi ketika saya masuk ke mode offline, permintaan datang kembali dari cache-disk bukan dari pekerja layanan.

Saya kira itu karena mengambilnya dari cache otomatis browser, tetapi jika saya mengklik opsi "Nonaktifkan cache" di Chrome, halaman offline tidak dimuat.

Apakah ada yang tahu mengapa hal ini terjadi?
