### Problem\n stores its in-flight flag inside the effect. If a component rerenders with a new poll callback while the old promise is unresolved, the effect is recreated with a fresh flag. An interval or visibility event can then start another poll before the original completes.\n\n### Reproduction\n1. Enable polling and let the first poll return a pending promise.\n2. Rerender the hook with a new callback.\n3. Fire a visibility event or advance the interval.\n4. Observe the new callback running while the first promise is still pending.\n\n### Expected behavior\nThe no-overlap guarantee survives effect recreation; polling resumes with the latest callback only after the active promise settles.\n\n### Proposed fix\nKeep the active promise in a hook-level ref and clear it with identity checking, plus a rerender regression test. -- This is an automated message from the Apache Git Service.
