Creating a pop-out iframe with adoptNode and "magic iframes"
I explored the concept of "magic iframes" and using adoptNode to move iframes between windows. Initially, I thought I'd found a way to preserve iframe state during the move. However, after discussing with Jake Archibald, it turns out that appendChild already handles node adoption, making adoptNode redundant. Furthermore, moving iframes causes them to reload, negating the perceived benefit. While moving DOM elements between documents is still interesting, the original premise for iframes doesn't hold. The post includes a demo and discusses the potential of the <portal> API.
