The following layout test is failing on MacOS High Sierra+ WK1
Issue seems to have been introduced within recent weeks. The diff shows a very small change in the position of several boxes. A reproduction and regression needs to be done.
Regressed this change to https://trac.webkit.org/changeset/236541/webkit
I used command:
run-webkit-tests --root testbuild-236541 animations/stacking-context-fill-forwards.html --iterations 500 -f -1
this command will reproduce the flakiness consistently.
running this with 236540 causes no failures.
It seems this issue has been resolved. running the same command on a newer spade yeilds zero failures.
run-webkit-tests --root testbuild-238794 animations/stacking-context-fill-forwards.html --iterations 5000 -f -1
marking issue resolved
