• Check if updating to the latest Preact version resolves the issue

Describe the bug
This is a bug related to Preact with Next.js. When an exception is throw in the render phase of a clientside rendered page the Next.JS pages/_error fails to render.

Using the latest Preact@10.7.3 and Next.js@12.1.6 and React@18.1 installed, changing the route (e.g. calling Router.replace, Router.push) will throw three errors(Local development):

1. Error: Cancel rendering route
2. Uncaught (in promise) TypeError: startTransition is not a function
3. Uncaught TypeError: startTransition is not a function
   

To Reproduce

• Demo
• Repo

Steps to reproduce the behavior:

1. Go to Demo
2. Open DevTools
3. Click on any of the post links, page does not navigate to the specified page
4. See error
   

Expected behavior

The page navigates to the specified link as expected.

Notes

What is the reason for having React 18 installed alongside Preact?

I use React while developing and only replace it with Preact in production.

The same as mentioned in #3233, even if I add pages/failing and pages/_error, when an exception is throw in the render phase of a client-side rendered page the Next.js pages/_error fails to render.
