The following layout test fails on EFL WK2
Above 200 last attempts gave only FAIL results. Missing elements: mi, mn, mtext.
Committed r202732: <http://trac.webkit.org/changeset/202732>
The problem is with the datalist element. It seems that EFL does not dump the text content contrary to other ports. The use of datalist in the test is not really valid and I'm not sure what's the support status of that element. That specific element is not really relevant for the MathML test so I just regenerated the reference on EFL.
