The following tests are failing after r159572: fast/forms/ValidityState-valueMissing-002.html fast/forms/access-key-for-all-elements.html fast/forms/access-key.html fast/forms/focus-selection-input.html fast/forms/focus-selection-textarea.html fast/forms/legend-access-key.html fast/forms/select-accesskey.html http://trac.webkit.org/changeset/159572 The tests all check for the 'Mac OS X' substring in the navigator's user agent, and adjust the expected keys based on that.
fast/dom/access-key-iframe.html regressed with r159572 as well.
All these tests seem to be passing again after r169799 <http://trac.webkit.org/r169799>. The next gardening patch removes the failure expectations for these 8 tests (and some others) https://bugs.webkit.org/show_bug.cgi?id=134665.
