There's a need for some space in a web browser that is reserved for browser messages. This space has to be distinct from space that can be used to display content, otherwise the website can spoof browser notifications. Of course, this has to be balanced with the desire to devote as much space as possible to content and have the browser get out of the way of the browsing experience. But any browser notification that's displayed only in space that's otherwise content is just asking for trouble.
