Crashes when browser storage is blocked #14325
Description
Reproduction
Easiest way to reproduce it is visiting https://reactrouter.com since it has the same issue.
- Block all storage in your browser settings (cookies etc.)
- Visit reactrouter.com
- Navigate to "Docs"
- Page breaks with
SecurityError: Failed to read the 'sessionStorage' property from 'Window': Access is denied for this document.
Seems to be linked to scroll restoration, but removing doesn't fix the issue for me. For us this is a real issue in production for users blocking storage in their devices.
