editing/undoundo-iframe-location-change.html fails depending on the other tests run before it. I found a test case that would make it fails all the time (other may work too). To reproduce this bug, just type: WebKitTools/Scripts/run-webkit-tests --debug LayoutTests/editing/pasteboard/drag-image-in-about-blank-frame.html LayoutTests/editing/undo/undo-iframe-location-change.html
Created attachment 23747 [details] Make the test slightly more reliable This doesn't fix the problem (and I don't know how to fix it), but makes the test slightly more reliable. Also, the test can now be run in Safari, where it doesn't pass at all, as it turns out.
