I do agree that there's still need for storing data while in private
browsing mode. So I do think it makes a lot of sense for
.sessionStorage to keep working.

But I do have concerned about essentially telling a website that we'll
store the requested data, only to drop it on the floor as soon as the
user exits private browsing mode (or crashes).
