All data within the first-party isolation needs to be cleared for detected bounce trackers. Make sure that iframes can't keep their state.
Rough sketch of the test:

* a.com
  * -> bounce.com
    * iframe=c.com (Total cookie protection doesn’t protect
  * -> d.com
* PURGE bounce.com
* Then a.com
  * -> bounce.com
    * iframe=c.com (STILL HAS THE partitioned COOKIE FROM BEFORE)
  * -> d.com

All data within the partitionKey needs to be cleared for detected bounce trackers. Make sure that iframes can't keep their state.
Rough sketch what should be protected from:

* a.com
  * -> bounce.com
    * iframe=c.com (Total cookie partitions this with partitionKey=bounce.com)
  * -> d.com
* PURGE bounce.com
* Then a.com
  * -> bounce.com
    * iframe=c.com (STILL HAS THE partitioned COOKIE FROM BEFORE due to same partitionKey=bounce.com)
  * -> d.com
