editing/pasteboard/paste-4039777-fix makes a selection, then copies and pastes in place. As far as I can tell, that should never change the content, however starting with <http://trac.webkit.org/projects/webkit/browser/trunk/LayoutTests/editing/pasteboard/paste-4039777-fix-expected.png?rev=15918>, it does. Most recently the result looks like this <http://trac.webkit.org/projects/webkit/browser/trunk/LayoutTests/editing/pasteboard/paste-4039777-fix-expected.png?rev=21197>. The expected results in the tree do not make sense to me.
