title: Is PWA supposed to work only for SPA?
body: <p>I'm trying to convert a webview based app to PWA. This app isn't SPA, the app full page-reloads for links and also performs regular form POST submissions.</p>
  
  <p>Something that I notice is that the scope (manifest.json) for POST seems to be outside of the app scope. When I submit a form POST, it opens like a page outside of the scope, then automatically closes it, and process the response from the submission in the background/standalone page. </p>
  
  <p>manifest.json:</p>
  
  <p><code>{
    /* description/name/icons attributes */
    "display": "standalone",
    "start_url": "dashboard/classes?utm_source=web_app_manifest",
  }</code> </p>
  
  <p>Is that expected? </p>
