Using useDeferredValue and Suspense unexpectedly shows fallback in ios/android but correctly shows stale state in web

Description

I'm following the examples from React on using useDeferredValue and Suspense to show a stale state. The correct behavior should be to show the fallback only on the first load, and then on subsequent queries (e.g. when typing in the search box or incrementing counter in the examples) show a stale state until new data is loaded (which then should replace the stale state). I've included an expo snack.

The correct behavior is observed in React Native web. However for android/ios the fallback always shows. For the snack I'm using React Native 0.76.7, which is the default version that a new expo project installs. I've also tested on 0.77.1 but get the same behavior.

In my actual project where I have ios/android folders I've tried explicitly setting newArchEnabled/isConcurrentRootEnabled like some of these older articles suggest, see here. However, the same behavior is observed with that as well.

Steps to reproduce

1. Go to the expo snack https://snack.expo.dev/@polarwang/reactnative-suspense-usedeferredvalue-bug

No response

Inizia con il reproducer Expo Snack collegato e confronta il suo comportamento di React Native su iOS/Android con React Native web. Esamina il flusso dell'esempio useDeferredValue e Suspense descritto nell'issue, quindi verifica che la versione nativa mostri il fallback solo al primo caricamento e contenuti obsoleti durante le query successive.
