Webkit转换未同步

Question

我目前正在研究CSS中的页面翻转效果。我已经设法做了一些非常有说服力的事情，但我对基于webkit的浏览器存在问题

使用chrome和firefox测试此链接，您将看到问题：

HTML

<div id="page-flip" class="animate">
    <div id="frontface">
        <div class="page">
            <div class="content">
                <div class="shadow">PAGE 1</div>
            </div>
        </div>
    </div>
    <div class="investigation-container">
        <div class="span12">
        PAGE 2
        </div>
    </div>
    <div id="backface">
        <div class="page">
            <div class="content">
                <div class="shadow"></div>
            </div>
        </div>
    </div>
</div>

<a href="#" style="color:#FFF; position:absolute; top:0px; left:0px; z-index:500;" onclick='$("#page-flip").toggleClass("turn"); return false;'>Toggle page turn</a>

    background: -moz-gradient(linear, left top, right top, from(rgba(0, 0, 0, 0)), to(rgba(0, 0, 0, .20)));
}

转换未与webkit同步导致页面被隐藏（#frontface .page .content）。我想知道我能做些什么来防止这种行为并且像firefox一样有一个漂亮而干净的过渡？请记住，它最终设计为在iOS上...

非常感谢！
