If the query container does not have a principal box, or the principal box is not a layout containment box, or the query container does not support container size queries on the relevant axes, then the result of evaluating the size feature is unknown.
For example, inline elements can have container-type: size but they don't support size containment, so @container (width >= 0) shouldn't match.
<!DOCTYPE html>
<style>
span { container-type: size }
@container (width >= 0) {
b { color: red }
}
</style>
<span><b>Shouldn't be red</b></span>
