title: WPF KeyTrigger not triggered when KeyBinding exists
body: <p>In my WPF application, I have a <code>TextBox</code> that has a <code>KeyBinding</code> and <code>KeyTrigger</code> on it, but it seems that the <code>KeyTrigger</code> is not invoked.</p>
  
  <p><strong>MainWindow.xaml</strong></p>
  
  <pre><code>&lt;Window
      x:Class="MainWindow"
      xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
      xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
      xmlns:i="http://schemas.microsoft.com/expression/2010/interactivity"
      xmlns:ei="http://schemas.microsoft.com/expression/2010/interactions"
      Title="MainWindow" Height="350" Width="525"&gt;
  
      &lt;TextBox&gt;
          &lt;TextBox.InputBindings&gt;
              &lt;KeyBinding Key="Return" Command="{Binding LogCommand}" CommandParameter="from KeyBinding"/&gt;
          &lt;/TextBox.InputBindings&gt;
          &lt;i:Interaction.Triggers&gt;
              &lt;ei:KeyTrigger Key="Return"&gt;
                  ...
              &lt;/ei:KeyTrigger&gt;
          &lt;/i:Interaction.Triggers&gt;
      &lt;/TextBox&gt;
  &lt;/Window&gt;
  </code></pre>
  
  <p>Is there any way to invoke both of them? I want to do this because there is something I don't want to do in ViewModel.</p>
