Changes to DOM properties (not attributes) do not appear to trigger observers today. E.g.:

    Object.observe(window.navigator, console.log.bind(console));

Now go offline. 

We should observe that this logs a change to window.navigator.onLine, but currently does not.

This property, e.g., is specified as a readonly attribute and not a getter, and therefore should be observable:
