fast/forms/number/number-spinbutton-click-in-iframe.html started failing on Apple Win 7 Release (Tests) between r128423
introduced in https://trac.webkit.org/changeset/128423,
but fails on Win Platform,
- PASS testInput.value is "12346"
+ FAIL testInput.value should be 12346. Was 12345.
Same failure as in https://bugs.webkit.org/show_bug.cgi?id=96634
Add it to Skipped in http://trac.webkit.org/changeset/129183.
It fails because RenderThemeSafari doesn't have spin button support.
