The output comes from some other test that runs before this one (but not immediately preceding it):

16:43:06.130 4812 worker/0 http/tests/navigation/onload-navigation-iframe-2.html passed

All the "page-cache" tests above use the helper file that contains the "This page should go back..." error. I suspect that page cache tests confuse Windows DumpRenderTree.

Per Arne, do you know if this is still an issue?
