 - `cookies.set()`: 
 As described the Abuse Mitigations section, this method will not allow a `hasCrossSiteAncestor` value of false, if the URL associated with the cookie and the `topLevelSite` in the `partitionKey` are not first-party. If this is attempted, an error will be returned. If a `hasCrossSiteAncestor` value is provided without a corresponding `topLevelSite` value, an error will be returned. Additionally, if no `hasCrossSiteAncestor` value is provided it will be populated using the algorithm described above.
