WPT details: No, unfortunately. Since this feature runs off of a long duration timer we cannot construct a WPT test case. We need wpt#17489 to be fixed in order to correct this: https://github.com/web-platform-tests/wpt/issues/17489
This feature mitigates bounce tracking on the web. It works by deleting state from sites that access storage during a redirect that the user has never directly interacted with. See the specification for more details.
Redirects can be used to implement cross-site tracking of users. In addition, redirects can be used to simulate third-party cookies even when the user has chosen to block third-party cookies. The primary goal of this effort is to mitigate these privacy issues.
