Describe the bug

Client navigation breaks with custom client.tsx. I suspect hydration is completely broken, but client navigation is the most directly visible issue.

Your Example Website or App

https://github.com/jakst/tss-client-reload

Steps to Reproduce the Bug or Issue

1. pnpm install && pnpm dev
2. Open app in browser. Navigate around. Notice all navigations go to the server.
3. Delete the file ./src/client.tsx and restart the dev server
4. Repeat step 2, and notice that client navigation works again.

Expected behavior

I expect client side routing to work with a custom client.tsx.
