The aforementioned test times out (FAIL: Timed out waiting for notifyDone to be called) both on the mac-wk2 bots and locally. Going to skip it.

jessie filed another one on a page-cache test timing out in webkit2 yesterday... was it the same? (I can't find it right now because searching on bugzilla is the worst experience ever)
Nope, those bugs were about
fast/harness/page-cache-crash-on-data-urls.html and fast/harness/use-page-cache.html (https://bugs.webkit.org/show_bug.cgi?id=81616)
We had the same problem in the Qt port (see https://bugs.webkit.org/show_bug.cgi?id=83576) of WK2 and for us, it turned out that the certificate needs to be accepted (which was already implemented in DumpRenderTree on both ports).
The solution for the Mac will most probably be somewhat different, but if you're interested, you can find the patch that fixed it for Qt here: http://trac.webkit.org/changeset/117045
I believe this was fixed by http://trac.webkit.org/changeset/121913 for https://bugs.webkit.org/show_bug.cgi?id=90600. I am going to stop skipping this for mac-wk2.
Unskipped the test in http://trac.webkit.org/changeset/148693
