Local storage and server side ID

Hey all,
If i would use LocalStorage as the storage strategy for the JS tracker (https://snowplowanalytics.com/blog/2017/05/18/snowplow-javascript-tracker-2.8.0-released/) am i right in thinking that 3rd party cookie blockers will not block the ID that is set with the Clojure collector?
