CORS issues

Question

Code example
https://stackblitz.com/edit/stuck-directive (code + preview)

Problem
As you can see, in the StackBlitz preview pane, I have JavaScript issues (I think due to CORS).

Question
Is there a workaround? Maybe we can fallback to a rect(0, 0, 0, 0)? Otherwise, I expect it to silently fail instead of console errors.

There seems to be an issue with IntersectionObserver in iframes. #3 has the link to the W3C issue.

I will add a warning to the console when trying to initialize within an iframe rather than show the error messages.
