Summary Invert random() caching behavior to match spec

The CSS spec for random() changed so that the `--foo` in `random(--foo)` is matched globally to the document rather than scoped to the element. This is the opposite of the behavior shipping in WebKit, and will create significant compat problems for this feature if it's not updated soon. See https://github.com/w3c/csswg-drafts/issues/13132#issuecomment-3998898114 and https://github.com/w3c/csswg-drafts/commit/54b0b4f123ca2dd6c1af33bfc08eca64cf8e1640
