access denied error thrown when cookies disabled

**Environment:**
Chrome browser on MacOS

**Reproduce Steps**

1. In incognito window mode of chrome browser
2. toggle "disable cookies" button
3. try loading the script , it fails accessing localStorage since the localStorage property exists but access is restricted

the handling in the current code is checking if property exists instead it should gracefully handle it by catching the exception and polyfill it.

**Error**
Uncaught SecurityError: Failed to read the 'localStorage' property from 'Window': Access is denied for this document
