--- Comment #3 from Joseph Pecoraro <joepeck at webkit.org> ---
Some notes after talking with johnwilander:

Cookie partitioning can happen per-frame and can change dynamically throughout the lifetime of the frame.

Some examples of dynamically changing:

  (a) Default iframe cookies are not partitioned
  (b) Tracker classified frames are partitions
    - User Interaction in a frame can dynamically change that frame's cookies to be not partitioned
  (c) New Storage Access APIs
    - If user allowed can dynamically change that frame's cookies to be not partitioned

There may also be the case that a time period expires and cookies go back to being partitioned.

The fact that this is per-frame raises a few interesting points for Web Inspector. There may be an A.com page with multiple B.com subframes, and one of the B.com subframes can be dynamically promoted to not partitioned. In this case Web Inspector would want to show both the (B) non-partitioned cookies and the (A/B) partitioned cookies.
