Bug report

Description / Observed Behavior

After updating to 2.4.0, our app (a client-side Next.js app bundle using Next 16.1.6) doesn't consistently fetch data on page load / refresh.

Also affects the app when running with the local development server (note: we have Turbopack turned off).

Expected Behavior

With 2.3.8, our app fetches data consistently.

Repro Steps / Code Example

Haven't been able to narrow down a minimal reproduction yet.
