Hi, I'd like WebKit's position on the proposal: Add sizes=auto to lazy-loaded <img> This allows web developers to omit the `sizes` attribute, or explicitly specify `sizes=auto`, for <img> elements that have `loading=lazy`. The browser will use the layout width of the image as input to the srcset resource selection (lazy images don't start loading until layout is known, at the earliest). For eager-loading images, it's invalid and equivalent to `100vw`.
