Compound interpolated expressions throw "Invalid prelude for @media csstree/validator"

[pinkhominid]

With version 2.1.0, using the postcss-lit custom syntax, compound interpolated expressions like this error

    @media (min-width: 500px) and ${namedMedia.css.mobile} {
        /* ... */
    }

whereas this doesn't

    @media ${namedMedia.css.mobile} {
        /* ... */
    }

I believe that isStandardSyntaxAtRule is now gone from Stylelint@16:

Mentioning this here because in the previous ticket this method was mentioned as the source of my issue. If this should be a new ticket let me know and I will create one.
