Description Csaba Osztrogonác 2014-02-20 05:03:53 PST

Tested on Mac Mavericks and it is still valid on ToT, but unfortunately the 
new regression caused by http://trac.webkit.org/changeset/164417 hides it.

But you can easily reproduce it on r164416.

test log:

Comment 1 Csaba Osztrogonác 2014-03-14 04:16:17 PDT

It works now on ToT.
