Where to setup link options?

[Zeka]

Hi.

There ProcessPageEditLink where we can specify some options for links.

But, in my case, every link gets also 'noreferrer', 'noopener' and doesn't get 'external' class.

If I'm not mistaken, I remember that I have setup this elsewhere, but can't remember where))

Are there options somewhere else? Why 'external' class doesn't populate?

Wow... I have actually never seen this before but for external links I use:

That's because of HTML Purifier (CKE editor/field settings) and links transformation (addition).
Probably because security suggestions for target="_blank" links to add attribute rel="noopener noreferrer" (more about that here, or...).
But if you want to change that behaviour, maybe there is some option to set/change HTML Purifier module configuration (from outside).
