[Bug]: prerender causes page to be duplicated/rendered twice in RW projects using React18

[Tobbe]

What's not working?

If you enable prerendering on a page it'll get rendered twice

How do we reproduce the bug?

yarn create redwood-app --ts --git rw-react18-prerender
cd rw-react18-prerender
yarn rw upgrade -t canary
yarn rw g page home /

Enable prerendering of Home

diff --git a/web/src/Routes.tsx b/web/src/Routes.tsx
index 2c8f02a..e398080 100644
--- a/web/src/Routes.tsx
+++ b/web/src/Routes.tsx

 const Routes = () => {
   return (
     <Router>
+      <Route path="/" page={HomePage} name="home" prerender />
       <Route notfound page={NotFoundPage} />
     </Router>
   )

yarn rw build
yarn rw serve

Go to http://localhost:8910 and you'll see the page rendered twice.
(If you turn off javascript it'll only be rendered once)

What's your environment? (If it applies)
