Re: [csswg-drafts] [css-sizing] Auto-resize iframes based on content (#1771)

Regarding "use cases" - Consider all 3rd party content, like user comments (disqus), videos, maps, tweets, facebook feeds, calendars, gists, ads, etc... it would be much safer if they were in an `<iframe>`, using their own isolated process ([ref spectre](https://w3c.github.io/webappsec-post-spectre-webdev/)), and did not involve the host website including an unsafe/dangerous 3rd party `<script>` (which grants far too much access).

I should also note that before [Safari 13 on iOS](https://developer.apple.com/documentation/safari-release-notes/safari-13-release-notes#Removed-Features), iframes were re-sized automatically (to avoid the scroll bar), with none of these security considerations.
