Feature request: Auto-resize iframes based on content

After the recent removal of the @seamless attribute on the <iframe> from the WHATWG spec:

https://github.com/whatwg/html/issues/331

We still need to consider the problem of setting the height of iframes, so they contain their content without scroll bars.

As discussed at:

https://github.com/whatwg/html/issues/555
https://lists.w3.org/Archives/Public/www-style/2016Jan/0236.html
https://lists.w3.org/Archives/Public/www-style/2016Feb/0004.html

The solution may simply involve the CSS:

#iframe { height: max-content; }

And a header on the framed content, rather than custom/buggy JavaScript.

I'm keeping my notes on:

Alternatively we could look at a new keyword for the resize[1] property, which would be useful for a <textarea> that automatically increases its height based on its content - another problem which requires JavaScript to solve.
