在PC上完成了我的导航栏，并将代码共享到我的iPhone上，以查看横向和纵向。在风景中，导航栏在右侧溢出。为非遮挡目的视图添加了 env（safe-area-inset） 值，但在右侧溢出。似乎找不到问题所在。
iPhone (11 Pro Max) Landscape Orientation左侧间隙是安全区env（），但右侧安全区间隙被导航栏溢出。
下面是一个例子：

我和一个朋友尝试了不同的改变，比如margin-padding，align-items，list-style，overflow，display，width/max-width属性。所有这些都导致导航栏内的内容移位或错误大小。
