菜单按钮显示在 safari 的下一行

Question

真正奇怪的问题。菜单按钮显示在 safari（浏览器和 iPhone）的下一行。这在 chrome 和 android 上正确显示。

糟糕的 Safari 请注意，菜单按钮不在黑条上。

不错的 Chrome

这是我的代码。这是Fiddle

//make the topnav responsive for mobile screens
function topNav() {
  var x = document.getElementById("myTopnav");
  if (x.className === "myTopnav") {
