Vite fast refresh not working #7419

Which project does this relate to?

Router

Describe the bug

When using react router v1.170.3 if in my __root.tsx file if I use createRootRouteWithContext to create my route Vite fast refresh doesn't work.

I get the error:

[vite] (client) hmr update /src/css/index.css, /src/routes/__root.tsx
[vite] (client) hmr invalidate /src/routes/__root.tsx Could not Fast Refresh ("Route" export is incompatible). Learn more at https://github.com/vitejs/vite-plugin-react/tree/main/packages/plugin-react#consistent-components-exports

If I use createRootRoute I don't see the error in the terminal.
