This is surprising, as the stream filter should be able to intercept any scripts requested by the site.

Do you by any chance have a more complete example (e.g. a webpage where librejs fails like this)?

original submission:

> On this page: <https://static.fsf.org/nosvn/demos/matomo/>, Matomo's JS inserts a script tag that links to a JS file that is supported by LibreJS. However the script is not mentioned in LibreJS' report, which leads me to believe that it doesn't check the license of that script.

Do you mean the following script?  It is accepted by LibreJS in my test.  Could you confirm whether it is still not tracked by LibreJS?

<script type="text/javascript">/* LibreJS: script accepted. */
// @license magnet:?xt=urn:btih:cf05388f2679ee054f2beb29a391d25f4e673ac3&dn=gpl-2.0.txt GPL-2.0-or-later
  var _paq = _paq || [];
  _paq.push(["trackPageView"]);
  _paq.push(["enableLinkTracking"]);

  (function() {
    var u = (("https:" == document.location.protocol) ? "https" : "http") + "://"+"matomo1p.fsf.org//";
    _paq.push(["setTrackerUrl", u+"piwik.php"]);
    _paq.push(["setSiteId", "18"]);
    var d=document, g=d.createElement("script"), s=d.getElementsByTagName("script")[0]; g.type="text/javascript";
    g.defer=true; g.async=true; g.src=u+"piwik.js"; s.parentNode.insertBefore(g,s);
  })();
  // @license-end</script>
