Research direction
No source file, test, or entry point is named. Reproduce the reported repeated-render behavior from the useImperativeHandle/ref snippet, then trace the virtual-list ref and render paths; done means the reproduction no longer renders repeatedly while ref behavior remains correct, with a regression test added where appropriate.
