I can’t help but repeat the arguments I already gave.

The selectors matched by an element can’t depend on the result of the style applied on it, because that style depends on the selectors that matched it. At least, it can’t using pure CSS. The text color of a “<span>text</span>” with “span { color: blue; css-ignore: external }” is an undecidable problem and browsers, being software programs, can’t resolve undecidable problems.

The use cases that one would like to solve with “css-ignore” on css-ignore should rely on some other mechanism instead, like IFRAMES and Web Components.

Well, my apologies for mentioning the use-case on the first place. I should have come to the point at once.
About the 'potential blocking of popup' issue, the client have ordered the app for themselves, so most probably that's not going to happen, given that they requested for the 'whole experience'.

I'm kind of new to mailing lists, I'm not here to debate on programming ideologies and best practices. I just want to share my thoughts on how we can take CSS forward, and I hope someone could spare a minute for the idea. 
I'd insist that you go through my last mail, and let me know your thoughts on it.

  The popup might be blocked by the user.

  Feelings are irrelevant here.

  Reminds me of a guy who "upgraded" the doctype to a newer version.
  Newer doctype. Must be better. Lets do it. I call this fallacy "appeal
  to new technology". Applies to anyone who served XHTML as text/html.

  Your proposal is only justified by the problems that you created using
  your comfortable methodologies. So "don't do that then".
