When checking if the Browsing Context had been discarded in
HttpBaseChannel, if the load group was not available then it was assumed
to have already been discarded which was not always the case for private
channels after the private session had ended. This vulnerability affects
Firefox < 117, Firefox ESR < 115.2, and Thunderbird < 115.2.
