title: Why does setTimeout not work from the chrome devtools?
body: <p>Very simple test in chrome devtools</p>
  
  <pre><code> setTimeout(alert, 1000)
  </code></pre>
  
  <p>In Chrome devtools, nothing happens (it does return a timerId) but the timer never fires.
  In Firefox, this does open an alert box.</p>
  
  <p>Why would setTimeout not work from chrome devtools?</p>
  
  <p>Version 53.0.2785.101 (64-bit) on Mac</p>
  
  <p>Hmmm, found an interesting byproduct, closing devtools causes the code timeout to occur.  So it only happens when devtools is still open.</p>
