The value of unwrap atom is not updated when unwrap atom is referenced in atomEffect.

[3846masa]

Bug Description

When calling an unwrapped atom in an atomEffect, the value of the unwrapped atom is not updated.

This issue has been occurring since v2.10.2, so this is probably due to a change in the timing of the setSelf call, I think.

Reproduction code

import { atomEffect } from "jotai-effect";
import { atom, createStore } from "jotai/vanilla";
import { unwrap } from "jotai/vanilla/utils";

async function main() {
  const target = unwrap(atom(() => Promise.resolve("value")));

  {
    const store = createStore();
    store.sub(target, () => {});

    console.log("first", store.get(target));
    // next tick
    await new Promise((resolve) => setTimeout(resolve, 0));
    console.log("next tick", store.get(target));
  }

  {
    const effect = atomEffect((get) => {
      console.log("effect", get(target));
    });
    const store = createStore();
    store.sub(effect, () => {});
  }
}

main().catch(console.error);

Jotai v2.10.1

first undefined
next tick value
effect undefined
effect value

Jotai v2.10.2 ~ v2.11.0 (latest)

first undefined
next tick value
effect undefined

Thanks for reporting, I'll take a look. I've started debugging this, it looks like effect is not getting called again.
