[Bug]: cache doesn't return the same refrence to a resolved promise

Summary

The cache function generates a new promise reference on every call, causing the use hook to treat it as a new dependency. This results in an infinite fetch loop as getData() is continuously invoked on each render.

Details

The following code demonstrates an issue with the cache function, which leads to an infinite fetch loop when used with use

'use client';
import { use, cache } from "react";

export const getData = cache(() => fetch("https://jsonplaceholder.typicode.com/posts").then(res => res.json()));

export function Home() {
    const data = use(getData());

    return (
        <pre>{JSON.stringify(data)}</pre>
    );
};

Problem

The cache function is expected to memoize the result of a function call. However, it appears to return a new promise reference every time getData() is called, which causes the use hook to treat it as a new input on every render. This results in an infinite fetch loop.

Expected Behavior

The cache function should return the same promise reference for the same input, ensuring that use(getData()) only triggers a single fetch request.

Actual Behavior

Maybe the cache function creates a new promise reference on each call, leading to an infinite loop of fetch requests.

Environment
React version: >=19 ("^19.0.0")

Start with the cache reference page and reproduce the provided use(getData()) example to compare the documented behavior with React 19. Check whether the example or its explanation accurately describes promise identity for the same input; done means the reported infinite-fetch behavior is either resolved or the documentation clearly explains the supported usage.
