why-did-you-render: wrong message when useMemo re-renders

In the following case:

const A = () => {
   const obj = useMemo(() => ({
     // something big
  }), [a, b, c, d, e]);

 return <Child  obj={obj} />;
}

when the hook useMemo re-creates obj even if it’s deps deep equals, the message says A was re-rendered because if it, where in reality useMemo re-generated obj without a reason, but A is not re-rendered because of this.
