### One-sentence description Always set `rel="noopener"` with `target = "_blank"` for external domains. ### Why Using `target="_blank"` without `rel="noopener"` for external domains is a security vulnerability. * [source](https://www.tutorialdocs.com/article/html-opener-blank.html) * [source](https://developers.google.com/web/tools/lighthouse/audits/noopener) ### Expected behaviour `a` tags containing `target="_blank"` should also contain `rel="noopener noreferrer nofollow"`.
