https://github.com/WebKit/WebKit/pull/14694 was intended to fix imported/w3c/web-platform-tests/html/rendering/the-details-element/summary-text-decoration.html, and removed it from TestExpectations. The fix didn't work, so the test started failing in post commit. But EWS didn't tell us about it, because it has incorrectly applied the pre-existing failure exception. https://ews-build.webkit.org/#/builders/39/builds/7479 Ignored pre-existing failure: imported/w3c/web-platform-tests/css/css-fonts/cjk-kerning.html, imported/w3c/web-platform-tests/css/css-ui/text-overflow-028.html, imported/w3c/web-platform-tests/html/rendering/the-details-element/summary-text-decoration.html, imported/w3c/web-platform-tests/html/semantics/disabled-elements/disabled-event-dispatch.tentative.html
