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.
Consider
<!DOCTYPE html>
<style>
div {
container-type: inline-size;
}
@container (block-size >= 0px) {
p { color: cyan; }
}
@container not (block-size >= 0px) {
p { background: red; }
}
</style>
<div><p>Lorem ipsum</p></div>
block-size >= 0px doesn't match since the query container does not support container size queries on the block axis. But then not (block-size >= 0px) matches, which is wrong, since the negation of unknown is also unknown.
See https://drafts.csswg.org/mediaqueries-5/#evaluating
The negation of unknown is unknown.
