The test output is incorrect for this test. A focus ring and caret do show up in pixel results.
This results in failures for the following tests: editing/selection/caret-and-focus-ring.html fast/events/blur-focus-window-should-blur-focus-element.html
The tests covered by this bug were found to be passing consistently after moving from using the Skipped list to using test_expectations.txt. Their expectations were removed in r116122[1] (covered by bug #85591). Closing the bug. 1: http://trac.webkit.org/changeset/116122
Can you also confirm that the pixel results are also correct now? I think it's a good idea to unskip these tests, but I feel the bug should stay open, since it's likely still a problem.
