IMG和文本未在导航栏中的Bootstrap按钮中对齐

Question

所以我环顾了Stackoverflow，无法找到问题的解决方案

很奇怪的是

我在这里试试，codepen

<nav>
  <button class="btn btn-primary"> signed in as fermi 
    <img src="https://ui-avatars.com/api/?
     name=Fermi+Fang&background=0D8ABC&color=fff&rounded=true">
  </button>
</nav>

文本对齐中心完美，

但在我的实时代码中，它没有

img of my live code

好的，这是我的qazxsw poi

live code

有什么可能导致我的按钮中的文本和img无法正确对齐的线索？

谢谢，

相同大小的line-height。也许它适合你。
