Right! :-) And that behavior is already defined by the spec as-is (I think). Though it might be good to be a bit more clear on the distinction between iacvt and cyclic.

Related bonus information worth keeping in mind: [standard properties can also participate in a cycle](https://drafts.css-houdini.org/css-properties-values-api-1/#dependency-cycles), but they can't be "guaranteed-invalid", so they'll have to get `unset` in both iacvt and the cyclic case. This slightly "pollutes" the otherwise clean separation between iacvt and cyclic, unfortunately ... not a huge deal, though.
