Loirooriol has just created a new issue for https://github.com/w3c/csswg-drafts: == [css-sizing] Last remembered size relies on unclear `contain-intrinsic-size: auto` == https://drafts.csswg.org/css-sizing-4/#last-remembered > The [last remembered size](https://drafts.csswg.org/css-sizing-4/#last-remembered) of an element is determined by: > - At the time that [ResizeObserver](https://drafts.csswg.org/resize-observer-1/#resizeobserver) events are determined and delivered, if an element has [`contain-intrinsic-size: auto`](https://drafts.csswg.org/css-sizing-4/#propdef-contain-intrinsic-size), is capable of being a [ResizeObserver](https://drafts.csswg.org/resize-observer-1/#resizeobserver) target, but does not have [size containment](https://drafts.csswg.org/css-contain-2/#size-containment), record the current inner dimensions of its [principal box](https://drafts.csswg.org/css-display-3/#principal-box) as its [last remembered size](https://drafts.csswg.org/css-sizing-4/#last-remembered). > - At the time that [ResizeObserver](https://drafts.csswg.org/resize-observer-1/#resizeobserver) events are determined and delivered, if an element has a [last remembered size](https://drafts.csswg.org/css-sizing-4/#last-remembered) but does not have [`contain-intrinsic-size: auto`](https://drafts.csswg.org/css-sizing-4/#propdef-contain-intrinsic-size), remove its last remembered size. The checks for `contain-intrinsic-size: auto` are unclear because: - `auto` alone is invalid, it must be followed by a length. - `contain-intrinsic-size` is a shorthand. What happens if only one of `contain-intrinsic-width` and `contain-intrinsic-height` contains `auto`? I guess the check should be whether both `contain-intrinsic-width` and `contain-intrinsic-height` have `auto`? Or should the last remembered width and height be set or removed independently?
