title: WPF Are NotifyPropertyChangeds marshalled to the dispatcher?
body: <p>If I update a property that throws a NotifyPropertyChanged on a thread other than the bound control's dispatcher is the update forcibly marshalled to this dispatcher?</p>
  
  <pre><code>BackgrounWorker.Run() =&gt; { blah.Blahness = 2; // notifies property changed on BW, is this marshalled to the dispatcher? }
  </code></pre>
