&gt; &gt; This new test fails for me on Sierra.
&gt; 
&gt; What's the failure output? I don't have Sierra to test on...</span >

&gt; &gt; This is probably bad.  Either this should be a w3c test, or we should make
&gt; &gt; our own resources, or we shouldn't need these resources.
&gt; 
&gt; There are many other tests that are using testharness.js (for which there
&gt; are multiple copies)
&gt; Would using &quot;/js-test-resources/testharness.js&quot; be better?</span >
Probably.</pre>
