Proxy reference changes unexpectedly without updates

[s524797336]

Bug Description

Since version 2.1.0, state.obj reference keeps changing unexpectedly, while it worked as expected in version 2.0.0. Is this a bug or a feature?

import React from 'react'
import { proxy, useSnapshot } from 'valtio'

const state = proxy({
  count: 0,
  obj: {},
})

const TestComponent: React.FC = () => {
  useEffect(() => {
    const timer = setInterval(() => {
      state.count++
    }, 1000)
    return () => clearInterval(timer)
  }, [])

  const { obj } = useSnapshot(state)

  useEffect(() => {
    console.log('Why obj keep changing?', obj)
  }, [obj])

  return null
}

In this example, state.obj's reference changes continuously in version 2.1.0, even though obj itself is not being updated. This issue was not present in version 2.0.0.

Thanks for reporting. It's either #967 or #970.
Can you identify which causes it?
Try

pnpm add https://pkg.pr.new/valtio@967

or

pnpm add https://pkg.pr.new/valtio@970

Cannot install using the given command; it returns a 404 error.

I switched to using pnpm add https://pkg.pr.new/valtio@8b7f7bf for #967 and pnpm add https://pkg.pr.new/valtio@c3af924 for #970.

#967 works fine, but #970 does not.

Thanks for looking into it. I'll work on it.

#986 reverts #970.
