I'm so confused here. Why isn't this test not getting skipped? There is no point in keeping track of this bug. It's virtually impossible to fix it!
Then, close this ticket as WONTFIX. The reason why the test case wasn't skipped for WinCairo was that WinCairo's TestExpectations wrongly marked all editing/pasteboard tests as flaky. > editing/pasteboard/ [ Pass Failure ImageOnlyFailure ] r276579 fixed it.
