Re: [csswg-drafts] [css-contain-3] Inconsistent handling of known and unknown features jeopardizes backward compatibility (#7551)

> I think so. The consequence of that is that we no longer need the kleene logic for container queries, right?

Nothing changes there since queries may still evaluate to unknown dynamically, right? 

> If the [query container](https://www.w3.org/TR/css-contain-3/#query-container) does not have a [principal box](https://www.w3.org/TR/css-display-3/#principal-box), or the principal box is not a [layout containment box](https://drafts.csswg.org/css-contain-2/#layout-containment-box), or the query container does not support [container size queries](https://www.w3.org/TR/css-contain-3/#container-size-query) on the relevant axes, then the result of evaluating the [size feature](https://www.w3.org/TR/css-contain-3/#size-features) is unknown.
