Chrome currently does not seem to do any of this particularly well,
but when you click a notification from say the notification center
there should be some "going to the relevant site" going on. E.g. via
focusing a particular browsing context that spawned the notification.

We also want to enhance the API to support the scenario of the site
being closed but the notification still being alive, with the
notification being able to revive the site in some way and the site
being aware which notification was clicked (note that currently it
would no longer have a reference to that object).

Trying to brain storm as to what should be done when you click a
notification of a site that is no longer there. Navigating to a URL
was one idea. Starting up an event worker as outlined (roughly) in
http://annevankesteren.nl/2013/05/applifying might be a better idea.

Yeah, that's currently not described. You think we should leave that
to developers? That might work, although that leaves the questions
about the site being closed.

No worries, your input is much appreciated :-)
