The test reports that everything should be selected, but in the pixel results you can see that nothing is selected. To reproduce: run-webkit-tests editing/selection/select-all-005.html --pixel
The test changed in <http://trac.webkit.org/projects/webkit/changeset/17562>, where a <script> element was added as the first child of the <html> element, so now it selects just that element instead of the body. The original test (without the first <script>) still passes!
