Unknown at rule @container if it is nested in SCSS context

[shadow-identity]

Describe the bug

Svelte-check reports on nested @container rule inside of SCSS style sheet.

It does not report in CSS context or if the @container is not nested.

Reproduction

<style lang="scss">
    article {
        @container main (min-width: 80em) {
            grid-template-rows: 1fr;
        }
    }
</style>

Then run svelte-check and see this warning message:

        @container main (min-width: 80em) {
            grid-template-rows: 1fr;
