My app shell disappears and reappears on page reload, why?

[jasan-s]

I'm using SW precache v2 in my React App and webpack. However, I am not getting the same results. My app works offline but on page reload(offline or online) everything from the DOM disappears and gets fetched again, the results do come from the service worker: (see photo below). In contrast, this app shell demo, react-hn app, and thesession.org app dont even make a request on page reload. What I'm I missing?
