After a bit of investigation, it looks like making live preview work when offline in the browser is not possible. Since the current ChromeOS app is a packaged PWA, it will inherit the offline restriction from the browser.

The root cause is that the live preview is a thirdparty domain and lives inside a sandboxed iframe, which cannot use the offline cache and APIs browser wide across the domain due to the sandbox. So there is no way for us to cache the live preview loader pages in an iframe.

But we should be able to fix with with a proper native app for chromeos with a local server once we moved out of the packaged PWA builds for ChromeOS
