使用JavaScript的Chrome（webkit浏览器）中的好奇CSS转换行为......
var obj = document.getElementById('foooo');
// obj.style.transform == "";
obj.style.transform = "rotate(45deg)"; // works (another 2d transform)
obj.style.transform = "translate(-50px,0px)"; // fails as "" (bug?)
obj.style.WebkitTransition = "translate(-50px,0px)"; // fails as ""
obj.style.MozTransition = "translate(-50px,0px)"; // fails as ""
obj.style = "transform: translate(-50px,0px)"; // works (solution)
为什么会发生这种情况，或者这个错误是否可重复？
