title: JavaFX CSS styling of TextArea does not work
body: <p>I'm writing a simple JavaFX application, but I can't get some of the CSS styling to work.
  The problem is the <code>-fx-background-color</code> property for my <code>TextArea</code>.  </p>
  
  <p>This is the relevant CSS:</p>
  
  <pre><code>.text-area {
    -fx-font-family: Consolas;
    -fx-highlight-fill: #00ff00;
    -fx-highlight-text-fill: #000000;
    -fx-text-fill: #00ff00;
    -fx-background-color: #000000;
  }
  </code></pre>
  
  <p>All the fields perform as expected, except <code>-fx-background-color</code>, which apparently does nothing. I still have the default white background. As you can see in the picture, the <code>TextField</code> below, which has identical CSS, but does apply the background color as expected.</p>
