<pre>The way EWS works is that when there are failures, it runs the tests again, and if failures are the same, it rolls out the patch, and runs the tests once again to check whether the failure(s) are a regression.
This is what happened here - a flaky test failed twice in a row, and didn't fail on the third try. I don't think that there is anything actionable here for EWS - we probably shouldn't make it slower by trying even more times.
http/tests/contentextensions/font-display-none-repeated-layout.html flakily fails with this diff:

It's a bug in console support code that content blocker messages flakily depend on other state.</pre>
