The following test is failing since it was turned into reftest in r155100. EFL WK2 result can be found here: http://build.webkit.org/results/EFL%20Linux%2064-bit%20Release%20WK2/r159334%20%2811447%29/animations/cross-fade-background-image-diffs.html.
Closing this bug because the EFL port has been removed from trunk. If you feel this bug applies to a different upstream WebKit port and was closed in error, please either update the title and reopen the bug, or leave a comment to request this.
