Question

我正在尝试实现一个附加导航栏的bootstrap。似乎所有东西都按预期运行，但谷歌浏览器中出现了一个奇怪的问题。当您通过导航栏滚动时，导航栏上的某个鼠标滚轮事件会在其附加时触发，滚轮完全停止工作，直到发生其他鼠标输入（如移动或咔嗒声）。

只需将w3schools词缀示例直接复制到html文档并以chrome格式打开即可轻松复制。如果将鼠标放在屏幕顶部并尝试向下滚动，它将会捕获。任何鼠标移动都会恢复滚动，但它会使页面导航更加笨拙。我复制了下面的确切代码（未经编辑的w3schools）。

在firefox，edge或IE中似乎没有出现此问题。在实际的w3schools网站或测试服务上也不会出现这个问题。我相信这是由于在iframe中包装代码的一些交互
