title: Why don't I see multiple console.log() actions when bubbling up or propagating down with event listener?
body: <p><div class="snippet" data-lang="js" data-hide="false" data-console="true" data-babel="false">
  <div class="snippet-code">
  <pre class="snippet-code-js lang-js prettyprint-override"><code>const containers = document.querySelectorAll('div.container');
  
  
  containers.forEach(container =&gt; {
    container.addEventListener('click', e =&gt; {
      console.log('I am fired');
    }, true);
  });
  
  // containers.forEach(container =&gt; {
  //   container.addEventListener('click', e =&gt; {
  //     console.log('I am fired');
  //   }, false);
  // });</code></pre>
  <pre class="snippet-code-css lang-css prettyprint-override"><code>body {
    font-family: Lato;
  }
  
  .group {
    display: flex;
    justify-content: center;
    align-items: center;
    height: 100vh;
  }
  
  .container {
    background-color: #1f1f1f;
    color: #ccc;
    display: flex;
    flex-direction: column;
    justify-content: center;
    align-items: center;
    height: 100px;
    width: 100px;
    margin: 0 30px;
    cursor: pointer;
  }
  
  .container h2 {
    margin: 0;
    margin-bottom: 5px;
  }
  
  span {
    font-size: 12px;
  }</code></pre>
  <pre class="snippet-code-html lang-html prettyprint-override"><code>&lt;div class="group"&gt;
    &lt;div class="container" data-letter="A"&gt;
      &lt;h2&gt;A&lt;/h2&gt;
      &lt;span&gt;Subtitle&lt;/span&gt;
    &lt;/div&gt;
  
    &lt;div class="container" data-letter="B"&gt;
      &lt;h2&gt;B&lt;/h2&gt;
      &lt;span&gt;Subtitle&lt;/span&gt;
    &lt;/div&gt;
  
    &lt;div class="container" data-letter="C"&gt;
      &lt;h2&gt;C&lt;/h2&gt;
      &lt;span&gt;Subtitle&lt;/span&gt;
    &lt;/div&gt;
  &lt;/div&gt;</code></pre>
  </div>
  </div>
  </p>
  
  <p>Regardless if I bubble up or propagate down and I put a console.log message in the event handler, the console.log() message is only ever fired once. Shouldn't it fire every time it hits a new element in the DOM tree?</p>
