固定页眉和页脚在菜单打开时移动

Question

我在这个Angular应用中遇到问题，我的页脚和标题（仅限移动设备）在打开侧边栏菜单时跳了105px。该应用已托管here，您可以看到在移动设备上打开时会发生什么。但是，我无法在桌面版Chrome中重现它。

请使用这些凭据并点击任意频道，然后拉出侧边栏菜单以查看问题：

您应将主要可滚动内容放在<md-content></md-content>内，并可能添加md-scroll-y作为属性以防止x滚动。对于您的应用，您希望在此处围绕您的聊天区域，以便仅滚动而不是整个页面滚动。

以下是使用md-content的演示 https://material.angularjs.org/latest/#/demo/material.components.content
