[i]frame support

[ziebarthw]

This may already be on the road map. At this phase in the project there seems to virtually no support for content loaded into <[i]frame /> elements.

(perhaps it is blocked by #170 since window.frames would be a significant part of a comprehensive implementation?)

Content on the demo web page delivered via an <iframe src="more-product-details.jsp?id=1234"/></iframe> (inline, JS-generated, etc.) would be missing from the final output.

Hello @ziebarthw,
Thank you for opening this issue.
You are perfectly right, there is no support of frames for now in the browser.
We will prioritize the support of web apis according to their need in real use cases.

If you have an usage of the browser where iframe support blocks you, please share :)
