[Q] RecoilStateInfo.subscribers.components.name is "<component name not available>"

Hi there, I'm implementing some kind of devtool.

  const getInfo = useGetRecoilValueInfo_UNSTABLE();
  const info = getInfo(someAtomOrSelector);
  console.log(Array.from(info.subscribers.components));

With this code, I got something like

[
    {
        "name": "<component name not available>"
    },
    {
        "name": "<component name not available>"
    },
    {
        "name": "<component name not available>"
    }
]

It seems the count of the array is correct, but I couldn't get the components' names. All of my components are type of (...) => JSX.Element. How can I get the component name properly?

EDIT; recoil version "recoil": "^0.5.2"
