https://ews-build.webkit.org/#/builders/60/builds/16380 had a flakey stress-test failure but the EWS bubble on the bug (https://bugs.webkit.org/show_bug.cgi?id=231358) was still green. The flakey test I wrote for has been flakey since its introduction (https://results.webkit.org/?suite=layout-tests&test=inspector%2Fpage%2FsetShowPaintRects.html), which was surprising to me until I realized that EWS layout test stress-testing being flakey didn’t result in the bubble turning red to indicate there was an issue.
