following code gives false positive error
const Collapse = ({
children
}) => {
const containerRef = useRef(null);
return /* @__PURE__ */jsx("div", {
ref: containerRef,
children
});
};

export const Collapse: FC<{
children: ReactNode
}> = ({ children }) => {
const containerRef = useRef<HTMLDivElement>(null!)
return <div ref={containerRef}>{children}</div>
}
