title: Why can't I expand this event object in the chrome console?
body: <p>Simplified, what I'm doing is running this in the console:</p>
  
  <pre><code>window.onbeforeunload = function (e) {
      console.log(e);
  }
  </code></pre>
  
  <p>But in the console, when the event fires (by trying to "leave page" in the middle of writing an SO question) what I see is this:</p>
  
  <pre><code>Event {clipboardData: undefined, cancelBubble: false, returnValue: true, srcElement: document, defaultPrevented: false…}
  </code></pre>
  
  <p>With a little "i" graphic next to it. When I click the arrow next to it to expand the object in the console, nothing happens. The arrow turns to indicate that it has expanded, <em>but it doesn't expand.</em></p>
  
  <p>What am I missing here??</p>
