I was able to reproduce the failure at TOT using run-webkit-tests --iterations 100 --exit-after-n-failures 1 --force accessibility/mac/native-text-control-set-selected-textmarker-range.html --debug -f

It seems that the test is flaky failing since it was added at https://trac.webkit.org/changeset/281691/webkit. I was able to reproduce the failure at r281695 but not at r281691 because a testable revision was not available.
