fast/inline/nested-text-descendants.html is a ref test introduced in http://trac.webkit.org/changeset/103772
Qt seems to be the only port that doesn't pass it so suggest skipping it for now. I think it's possible to override a ref test with a platform-specific results file. This generates warnings but I think the results file is given preference.
