Issue is similar to #296 The fix in this issue is not applicable to me I think since I'm not running behind nginx.

• Web Browser: Google Chrome
• Local OS: Windows 10
• Remote OS: Ubuntu 20.04

Steps to Reproduce

1. Open any md file.
2. Try previewing the document.

Nothing in the code-server logs, But on dev tools,

Uncaught (in promise) Error: Service Workers are not enabled. Webviews will not work. Try disabling private/incognito mode.
    at main.js:115
    at new Promise (<anonymous>)
    at main.js:115

I'm not accesing it in incognito mode.
