No way these are related to this patch as it only impacts WK2.

This seems not quite right. Cookies with the same name but on different domains should be treated as different cookies.

Change log duplicate!

I don't think this is right.

Do we really need to define both? I thought defining hasIsEmptyValueFunction was enough.

Just use m_pendingCookies.removeIf instead of creating a temporary Vector?
