Comment 7 for bug 1502282

The tri-state accessibility comes straight from QNetworkAccessManager: http://doc.qt.io/qt-5/qnetworkaccessmanager.html#NetworkAccessibility-enum

There is a discussion thread here: http://www.qtcentre.org/threads/37514-use-of-QNetworkAccessManager-networkAccessible

I agree that the tri-state enum is useless. But the shell can't magically fix it, I suspect. The best option is probably to just assume that "Unknown" means the the same thing as "Not accessible". If bad things happen that way, so be it: inside the scope is the wrong place to fix this. It needs to be fixed in QNetworkAccessManager. (Failing that, maybe in the shell, but that still smells bad.)
