Bug: `use` function doesn't warn about uncached promise when promise doesn't resolve immediately

[tomdohnal]

When I pass an uncached promise that doesn't resolve immediately to the use function, (e. g. use(new Promise(resolve => setTimeout(resolve, 1000)))), I don't get the "A component was suspended by an uncached promise. Creating promises inside a Client Component or hook is not yet supported, except via a Suspense-compatible library or framework." warning.

Instead, I get into an infinite loop as the Promise keeps getting recreated.

(When I use a promise that gets resolved immediately, like use(new Promise(resolve => resolve()), I do get the warning message as expected)

React version: ^19.0.0

Steps To Reproduce

1. Go to https://codesandbox.io/p/sandbox/modest-merkle-cr7qcn
2. Open the preview and devtools
3. See there's no warning message about an uncached promise
4. See that the "hi from Promise" gets logged indefinitely

Link to code example:
https://codesandbox.io/p/sandbox/modest-merkle-cr7qcn

The current behavior

No warning message gets logged

The expected behavior

I get the "A component was suspended by an uncached promise. Creating promises inside a Client Component or hook is not yet supported, except via a Suspense-compatible library or framework." warning regardless of how long the promise passed to the use function takes to resolve.
