Code

const openInNewTab = true; // could be true or false

export default function App() {
  return (
    <a
      href="https://google.com"
      target={openInNewTab ? "_blank" : "self"}
      rel={openInNewTab ? "noreferrer" : undefined}
    >
      Open Google
    </a>
  );
}

Currently what's happening

If I pass target='_blank' based on some condition as shown in the above snippet, and pass rel='noreferrer' on same condition. It is still showing me warning/error as per the config.

What should happen?

Ideally if the condition is same for both the props it should recognise it and should not give us warning/error.

Please let me know if I am missing something?
