`rel="noopener"` not being added in normal external links is actually correct behaviour because @codinghorror is TL4 and `tl3 links no follow` is disabled.

`rel="nofollow noopener"` being added for @zogstrip (TL4) is a bug and onebox should respect the site setting `tl3 links no follow`.

There is a bug report for this here:

> Continuing the discussion from ["exclude rel nofollow domains" not respected inside of onebox](https://meta.discourse.org/t/exclude-rel-nofollow-domains-not-respected-inside-of-onebox/71533): It seems that even after whitelisting a website, onebox nofollows every link, including internal.

If the user is TL3 or above, `rel="nofollow noopener"` not being present is correct / as expected.
