The test is marked as ImageOnlyFailure in general test expectations, although is passing in several platforms (GTK, mac-wk2, ios-wk1). In WPE, the test started passing since r261996, although it's a flaky timeout.
For a timeout output, see: https://build.webkit.org/results/WPE%20Linux%2064-bit%20Release%20(Tests)/r262703%20(18494)/results.html
When there's a timeout there's this stderr output:
Failed to load 'about:blank', terminating process and trying again.
Failed to load 'about:blank' again after termination.
<unknown> - TestController::run - Failed to reset state to consistent values
#PROCESS UNRESPONSIVE - WPEWebProcess
