Reproduction link

Steps to reproduce

layout 中出现 layout-sider 时

What is expected?

按钮的点击事件应该只触发一次

What is actually happening?

dropdown-button的点击事件会触发两次

普通button是正常的，layout中不出现layout-sider时也是正常的

阻止冒泡事件【e.stopPropagation()】对此issue似乎可行，

业务组件中：

或者
components\dropdown\dropdown-button.tsx：

另外，我发现在有layout-sider时候，点击dropdown右边的按钮，也会触发click事件，所以需要在components\dropdown\dropdown-button.tsx中再给右边的按钮也阻止掉冒泡事件。

阻止冒泡虽然能解决这个触发两次的问题，但具体触发此问题的原因，还不明确。

感觉是 vue 的bug

[tangjinzhou]

不是冒泡的问题

不是冒泡的问题

组止冒泡的话是一个治标不治本的改法。但是具体为啥会有这个问题，水平有限，无法找到😕

是很奇怪，我发现绑定事件改成这样就正常了
