did anyone know how Remix handle the form resubmission problem?

when the JS is not available for some reason, and the form submission fall back to native browser behavior, how does remix prevent the form resubmission problem?

The typical technique is POST/REDIRECT/GET (PRG).

You should redirect from your action. This way if the user tries to refresh, the browser will not resubmit the form.

I discovered that the remix already addressed the issue without requiring the use of PRG. I'm curious to know how the remix achieved it.

I figured it out. it was the <ScrollRestoration /> component. it will call the window.history.replaceState function, which addressed the issue.
