Description
This feature did not make the v1 specification and therefore we should remove the support from the polyfill. It appears that [`:defined`](https://developer.mozilla.org/en-US/docs/Web/CSS/:defined) is the successor, but that is exactly the opposite of `:unresolved`.
Removal of this feature solves CSP compatibility and would thus resolve #188 and #969.
