This is limited to Sierra Debug WK2 according to the flakiness dashboard.
Comment 2 Ryan Haddad 2017-04-20 10:50:57 PDT
Marked test as flaky in https://trac.webkit.org/changeset/215562/webkit
Comment 3 Matt Lewis 2017-05-31 15:44:59 PDT
The Test has since started failing intermittently on Sierra Release WK2 as well according to the current dashboard.

First release failure was on 5/18 with build:
https://build.webkit.org/builders/Apple%20Sierra%20Release%20WK2%20(Tests)/builds/1578

They have the same diff.
I was unable to reproduce locally.
