What solutions exist today?

iframe or object

How would you solve it?

We propose the introduction of a new JavaScript Constructor Interface, WebViewPreview() or webview-preview element, which delegates the responsibility of content isolation and mandatory attribution UI to the User Agent (Browser).

This solution eliminates the need for developers to use complex server-side proxies or manually manage the security of <iframe> elements.

Anything else?

That covers everything for now. Thank you for your time and attention to this proposal.
