r126275 introduced fast/dom/shadow/shadowdom-dynamic-styling.html which currently fails on EFL. -PASS window.getComputedStyle(target).backgroundColor is "rgb(255, 0, 0)" +FAIL window.getComputedStyle(target).backgroundColor should be rgb(255, 0, 0). Was rgba(0, 0, 0, 0).
Seems to be passing as of r131039, unskipped in <http://trac.webkit.org/changeset/131040>.
