<pre>The Resource Timing tests included as part of the W3C Web Platform Tests are flaky under an upcoming patch for issue 161068.
The tests fails under these two circumstances:
1)
When PerformanceResourceTiming is created with a null ResourceResponse. This happens when memoryCache.resourceForRequest(..) (inside CachedResourceLoader::requestResource) returns a resource whose response (resource->response()) is null.
2)
When the onreadystatechange callback of an XHR or the onload callback of an added stylesheet is called, before the resource timing entry has been added to the timeline.
The imported/w3c/web-platform-tests/resource-timing/resource-timing.html test will occasionally run into one of the above cases and fail the test.</pre>
