Reftest mathml/presentation/fractions-box.html seems to be working for me on EFL when I open with mini-browser. I have many timeout with run-webkit-test and so does the buildbot so I can not really be sure, but I think we can unskip this test now.

I landed this test gardening without review and will watch the EFL bot.
