2 changes made

  • added a value.startsWith('--') pre-normalization check that operates in line with Remove automatic var(…) injection #13537 to prevent automatic var(…) injection when checking support for custom properties

    example: supports-[--test]:flex with vs. without with the value.startsWith('--') to prevent normalizing:

    • ❌ @supports var(--test) (before, without check)
    • ✅ @supports (--test: var(--tw)) (after, with check)

  • added hyphen-support for regex pattern matching raw supports queries


// Chrome has a bug where `(condtion1)or(condition2)` is not valid
// But `(condition1) or (condition2)` is supported.
