pagespeed css fetched by CDN result in cache-control:private,max-age=300 #494

Consider an HTML file:
  http://www.example.com/foo.html
with content
  <link rel=stylesheet type=text/css href=//example.cdn.com/foo.css />
which where foo.css content is
  .foo { background: url(/foo.jpg) }
The CDN is configured to fetch it from static.example.com.

The resulting fetch of the optimized CSS file
    http://example.cdn.com/foo.css.pagespeed.cf.HASH.css
will be served with response-header Cache-Control:private,max-age=300

This defeats one of the benefits of mod_pagespeed.
