当我将鼠标光标放在单词上时，工具提示必须出现在上方。它适用于所有浏览器。但是在 IE (v10) 中，当您将鼠标光标放在 div 工具提示（隐藏）上时，工具提示就会出现！请问我该如何处理？
演示：http: //jsfiddle.net/sd4tB/2/
编码：
<envelop class="enveloppe_bulaut"><aut class="comtip">clickme</aut><bulaut class="combulle"><div class="avatar_abo_bulle">toto</div><div class="texte_abo_bulle">tototototototo</div></bulaut></envelop>
