fast/multicol/newmulticol/spanner2.html is a flaky Image Only failure on High Sierra WK1 and Leaks according to the flakiness dashboard. https://webkit-test-results.webkit.org/dashboards/flakiness_dashboard.html#showAllRuns=true&tests=fast%2Fmulticol%2Fnewmulticol%2Fspanner2.html The image diff seems to just be a slight shifting of the image. The build: https://build.webkit.org/results/Apple%20High%20Sierra%20Debug%20WK1%20(Tests)/r222777%20(128)/results.html https://build.webkit.org/results/Apple%20High%20Sierra%20Debug%20WK1%20(Tests)/r222777%20(128)/fast/multicol/newmulticol/spanner2-diffs.html The first failure started with the first build after the High Sierra queues were brought up: https://build.webkit.org/builders/Apple%20High%20Sierra%20Release%20WK1%20(Tests)/builds/0
Does this reproduce when the test is run on its own?

I have been unable to get the test to fail locally.
This likely means that a preceding test does something that breaks subsequent tests. Can you check if that's the case, and bisect to the culprit if so?
