We have a couple of SVG animation tests that are flaky: svg/animations/animate-linear-discrete-additive.svg [ ImageOnlyFailure Pass ] svg/animations/animate-linear-discrete-additive-b.svg [ ImageOnlyFailure ] svg/animations/animate-linear-discrete-additive-c.svg [ ImageOnlyFailure Pass ] svg/transforms/transformed-text-fill-pattern.html [ ImageOnlyFailure ] svg/animations/mozilla/animateMotion-mpath-pathLength-1.svg [ ImageOnlyFailure Pass ]
> svg/animations/animate-linear-discrete-additive.svg [ ImageOnlyFailure Pass ] > svg/animations/animate-linear-discrete-additive-b.svg [ ImageOnlyFailure ] > svg/animations/animate-linear-discrete-additive-c.svg [ ImageOnlyFailure Pass ] > svg/animations/mozilla/animateMotion-mpath-pathLength-1.svg [ ImageOnlyFailure Pass ] These four are very very flaky on Mac WebKit2, too (but not WebKit1). Marked as such in <http://trac.webkit.org/r156367>.
We still have them - https://github.com/WebKit/WebKit/blob/7a5daf3137d24451085c7c65573bc787e5aac772/LayoutTests/platform/mac-wk2/TestExpectations#L522 and https://github.com/WebKit/WebKit/blob/7a5daf3137d24451085c7c65573bc787e5aac772/LayoutTests/platform/glib/TestExpectations#L1276 and https://github.com/WebKit/WebKit/blob/7a5daf3137d24451085c7c65573bc787e5aac772/LayoutTests/platform/ios-wk2/TestExpectations#L1143 and https://github.com/WebKit/WebKit/blob/7a5daf3137d24451085c7c65573bc787e5aac772/LayoutTests/platform/win/TestExpectations#L2249
Importing this blink adjustment might leads to non-flakiness - https://chromium.googlesource.com/chromium/src.git/+/a355f97c2b9962a162f7e96f92303deaa9fc97c2
