[Q/A] Safari storage state out of sync with Redux

[favorless]

What happened?

A bug happened!

I'm trying to use redux in background and popup, but there is a bug. After modifying the same redux state twice in the background, the second modification will not be captured by popup's useSelector

When I was troubleshooting the problem, I found that the state of the background store has changed, but the state of the popup is still the value that has been modified for the first time.

It is worth noting that he works stably and normally in chrome, but there will be problems in Safari

store.ts
//as same as with-redux template

reducer.ts
`
import { createSlice } from "@reduxjs/toolkit"

export interface CounterState {
enable: boolean
obj?: {
a: number
b?: {
c: number
d: string
}
}
}

const initialState: CounterState = {
enable: true
}

const counterSlice = createSlice({
name: "counter",
initialState,
reducers: {
setObj: (
state,
{ payload: { a, c, d } }: { payload: { a: number; c: number; d: string } }
) => {
return {
...state,
obj: {
a,
b: {
c,
d
}
}
}
}
}
})

export const { setObj } = counterSlice.actions

export default counterSlice.reducer
`

// background.ts
`setTimeout(() => {
store.dispatch(
setObj({
a: 1,
c: 2,
d: "hello"
})
)

setTimeout(() => {
store.dispatch(
setObj({
a: 2,
c: 3,
d: "hello again"
})
)
}, 2000)
}, 3000)`

// popup.tsx

const count = useSelector(state => state.counter)

useEffect(() => {
console.log(count, store.getState())
}, [count])

When the two setTimeouts are executed, the redux in the background is obj: {
a: 2
b: {
c: 3
d:'hello again'
}
}
And the value of popup's redux is obj: {
a: 1
b: {
c: 2
d:'hello'
}
}

I tried my best to restore the scene code I encountered when I was working. I suspect that the obj in the count is a reference type. When the store resync in the background was not monitored by the popup, the redux of the popup was not updated. Would you give me some suggestions about it? I would thank it a lot.
