Service Worker doesn't catch favicon requests

[lewispham]

Why doesn't Service Worker catch my favicon request?

<link rel="icon" type="image/png" href="/app/favicon-192x192.png" sizes="192x192">

sw.js

onfetch = function(e){
     //nothing happened
     console.log(e.request.url);
};

It should. I assume you're testing on Chrome? This is a Chrome implementation bug:

You've got the right point. From your link, it's hard to believe that Chrome deals with an issue by representing a new bug ~~. Thank you @mattto

Closing since this appears not to be a spec issue.
