Indeed.  I'm been on a multi-year odyssey to remove these cases.  I think this
situation is removed in the default settings for every port except the Mac
port.  My understanding is that future version of Safari will use a the
non-default setting but that we're worried about non-Safari clients of WebKit
relying on the old (insecure) behavior.
