Please correct me if I am wrong, but would not such a tracking be circumvented by enabling first party isolation in the browser? As far as I know, Firefox has such feature implemented: https://www.ghacks.net/2017/11/22/how-to-enable-first-party-...

I was also wondering about the that. Sadly, it is still not enabled by default in the latest Firefox release (version 70).

Furthermore would the Firefox Multi-Account Containers https://addons.mozilla.org/en-US/firefox/addon/multi-account... with container per site prevent such tracking (has to be done manually ATM) ?
