Catalina Release WK2 Perf tests are failing after https://trac.webkit.org/changeset/257189/webkit, seemingly because of this unexpected output that is present in every test: objc[87375]: Class WebOverlayLayer is implemented in both /Volumes/Data/slave/catalina-release-perf-tests/build/WebKitBuild/Release/WebCore.framework/Versions/A/WebCore (0x10a6e0368) and /Volumes/Data/slave/catalina-release-perf-tests/build/WebKitBuild/Release/WebKitLegacy.framework/Versions/A/WebKitLegacy (0x1079ad1d8). One of the two will be used. Which one is undefined. https://build.webkit.org/builders/Apple-Catalina-Release-WK2-Perf/builds/305
