Re: [csswg-drafts] [css-animations-2] Allow expressing width/height animations as scale animations (#13064)

This is not possible for width/height animations, though perhaps possible specifically for view-transition psuedos as they are absolutely positioned and only contained images.


> It’s this exact question of mine that sparked this issue. My original ask was an option on `document.startViewTransition` that indicates _“I want optimized keyframes”_. This could still become a thing in the future, built on top of what is being proposed in this very issue.

Why not `::view-transition { size-interpolation: scale; }` or some such as proposed?
