I have not yet tried reproducing this locally.

Marked test as flaky on El Capitan Release WK2 in http://trac.webkit.org/projects/webkit/changeset/209493

[Frédéric Wang (:fredw)]

Probably due to bug 174030. See also bug 179110

[Frédéric Wang (:fredw)]

I intend to enable a slightly different version of that test in bug 183628, that hopefully will allow to workaround bug 174030. Marking this as a duplicate.
