universal rendering: hydration does not happen

Describe the problem:

Flareact claims to support universal rendering (both ESR and CSR). However, code does not seem to ever run on the client after rehydration, and it does not seem possible to detect when you’re running client-side.

Link to a minimal reproduction:

import React from 'react'

export default function Index() {
 useEffect(()=>{ console.log('client effect') })
 return (
    <h1>
      should print something to console upon page load
    </h1>
  );
}

@jplhomer Well, that’s strange. Just tested on a fresh project and its working as expected. Tested with different flareact and react versions too… I had the same problem @wizzard0 had when useEffect wasn’t firing unless router is imported. Took me a while to find why some pages didn’t work. Don’t know what to make of this.
