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.

 // 'this' is lexically scoped in arrow functions

 var obj = {

     f: function (expected) {

         assertEq(this, expected);

         return a => this;

     }

 };

 var g = obj.f(obj);

 assertEq(g(), obj);

 var obj2 = {f: obj.f};

 var g2 = obj2.f(obj2);

 assertEq(g2(), obj2);

 assertEq(g(), obj);
