It looks like the changes in https://trac.webkit.org/changeset/241856/webkit most likely caused 5 API failures on Mac Log: https://build.webkit.org/builders/Apple%20High%20Sierra%20Release%20WK2%20%28Tests%29/builds/9628/steps/run-api-tests/logs/stdio build: https://build.webkit.org/builders/Apple%20High%20Sierra%20Release%20WK2%20%28Tests%29/builds/9628
These 5 API tests may be fallout from infrastructure downtime yesterday.
