title: title in h:head rendered before render response phase?
body: <p>I'm trying to set the value of the HTML title element (inside h:head element) dynamically based on view parameters.  I'm setting the value to be used in a preRenderView system event.  I've noticed that the EL to fetch the title is being evaluated before the preRenderView event is fired!  Why is that and is there anything I can do?</p>
  
  <p>If I grab the generated title value in a h:outputText somewhere in the page it is displayed as expected.</p>
  
  <p>Facelet:</p>
  
  <pre><code>&lt;h:head&gt;
      &lt;title&gt;#{myBean.title}&lt;/title&gt;
  &lt;/h:head&gt;
  </code></pre>
  
  <p>Bean:</p>
  
  <pre><code>public void preRenderView(ComponentSystemEvent event) {
      title = "Person: " + firstname " " + lastname; 
  }
  </code></pre>
