Ignore :has() selectors nested inside @supports rules

[romainmenke]

Bug description

@supports can now also check for selector features.

:has() should not be transformed if the stylesheet author made the selector conditional.

Source CSS

@supports (selector(:has(works))) {
  :has(foo) {}
}

Expected CSS

@supports (selector(:has(works))) {
  :has(foo) {}
}

Actual CSS

@supports (selector(:has(works))) {
  [\:has\(foo\)] {}
  :has(foo) {}
}

Does it happen with npx @csstools/csstools-cli <plugin-name> minimal-example.css?

Yes

Debug output

@supports (selector(:has(works))) {
  [\:has\(foo\)] {}
  :has(foo) {}
}
