So far this test has only failed one time and I could not reproduce with iteration testing

I am holding off on updating test expectations to see if this test starts to fail more

This is a weird one. The fact that the results aren't dumped as text implies that a support script wasn't loaded. Checking WPT server logs, I see that only parsing-testcommon.js, meaning that WebKit used a cached copy of testharness.js and testharnessreport.js. So the cached script failed to work?

Seems difficult to investigate without a repro case.

WebKit QA confirmed this is resolved
