Thanks for your reply, I was unable to find reference for the behaviour of relative urls within Iframes in the specs.

Would you happen to know where I could find this in the specs?

We're working on getting an isolated reproduction that I can send you a link to.

That sounds quite odd, and doesn't match the behavior of any browser I'm aware of.

Do you happen to have a link to a page that shows the behavior you're describing?

The correct behavior is that relative URLs in an iframe use the base URL of the iframe, which is the document URL of the iframe unless there's a <base> tag or the document URL is about:srcdoc or about:blank or javascript:something (and possibly some complexity around iframes whose content was generated via document.open/write/close).
