Interestingly, this works. You'd think that if I set the proxy to
manager it wouldn't work as I'd wanted, because this proxy role now has
permissions equal to that of manager, so I still couldn't check if
Anonymous can view. But apparently this isn't the case, and it does
work..

Could somebody explain this behavior?
