Conditionally enable double key logic according to:
private browsing mode or privacy.thirdparty.isolate preference and
implement in GetCookieStringCommon and FindCookie where it counts...
With some reservations of how to convince FindCookie users to test
condition and pass a nullptr when disabling double key logic.

      flag in the chrome is inapplicable, and we can't tell at this level
      whether we represent the particular DOM window that makes this decision
      for the chrome.
      So only this object (and its corresponding DOM window) knows whether
      scrollbars are visible. The corresponding chrome window will need to
      ask (one of) its DOM window(s) when it needs to know about scrollbar
      visibility, rather than caching its own copy of that information.
