Doesn't look like it is bot-specific http://build.webkit.org/results/Windows%207%20Release%20(WebKit2%20Tests)/r83588%20(5320)/results.html (fails, apple-windows-7) http://build.webkit.org/results/Windows%207%20Release%20(WebKit2%20Tests)/r83587%20(5319)/results.html (fails, apple-windows-7) http://build.webkit.org/results/Windows%207%20Release%20(WebKit2%20Tests)/r83586%20(5318)/results.html (fails, apple-windows-8) http://build.webkit.org/results/Windows%207%20Release%20(WebKit2%20Tests)/r83585%20(5317)/results.html (passes, apple-windows-7) http://build.webkit.org/results/Windows%207%20Release%20(WebKit2%20Tests)/r83584%20(5316)/results.html (fails, apple-windows-7) http://build.webkit.org/results/Windows%207%20Release%20(WebKit2%20Tests)/r83582%20(5314)/results.html (passes, apple-windows-7) It should be added to the win-wk2 skipped list.
... and now it is flaking on SL: http://build.webkit.org/results/SnowLeopard%20Intel%20Release%20(WebKit2%20Tests)/r83589%20(10606)/results.html I am going to add it to the mac-wk2 skipped list.
Added to the mac-wk2 skipped list in http://trac.webkit.org/changeset/83605

This test appears to work well on Mac now.
The test is green in the last 5000 revisions in all platforms: https://results.webkit.org/?suite=layout-tests&test=fast%2Fdom%2FStyleSheet%2Fdetached-stylesheet-without-wrapper.html Also, there's no more WebKit platforms referencing this bug in their TestExpectations. Marking bug as fixed.
