compositing/iframes/invisible-nested-iframe-show.html, compositing/tiling/huge-layer-add-remove-child.html have been failing on Windows 7 Release (Tests) since r88581. http://build.webkit.org/results/Windows%207%20Release%20(Tests)/r88579%20(13654)/results.html passed http://build.webkit.org/results/Windows%207%20Release%20(Tests)/r88581%20(13655)/results.html failed
It looks like these failures started with http://trac.webkit.org/changeset/88580. I am going to add the expected (failing?) results on Windows in order to get the bots green.
Added expected failing results in http://trac.webkit.org/changeset/88747.
