Here is an interesting case with our EWS + results DB integration, but I’m not sure how we’d mitigate it: https://github.com/WebKit/WebKit/pull/11769 was supposed to fix TestWebKitAPI.WebKit.MediaBufferingPolicy, and since EWS was ignoring the failure based on post-commit results, it ignored the fact that the test continued to fail with the PR and marked the run as ✅ https://ews-build.webkit.org/#/builders/18/builds/1253
