title: Vue-Bootstrap b-select option hover
body: <p>I'm using Vue-Bootstrap framework, I want to rewrite the css rule for tag 'option' when you hover the element</p>
  
  <p>My code is like this <a href="https://jsfiddle.net/3bvspfo2/13/" rel="nofollow noreferrer">jsfiddle</a></p>
  
  <pre><code>option:hover {
    background-color: red;
  }
  </code></pre>
  
  <p>Why the background-color in 'option:hover' change the background when is not hover event, and not when is a hover event?</p>
  
  <p>Thanks!</p>
