title: How to style movable tab in QTabWidget
body: <p>I got most of the styling done for my QTabWidget. My tabs are movable and closable. For some reason, the tabs are not rendering when I try moving them.</p>

  <p>Here's what it looks like after I try moving one of them:</p>

  <p>As you can see, the tab completely disappears. Am I missing something in my qss? Here is the stylesheet I'm using.</p>
  
  <pre><code>* {
      background-color: #3f4543;
      color: white;
      font-size: 12pt;
      margin: 0px;
      border: none;
  }
  
  QTabWidget::pane {
      border-top: 3px solid #535a57;
  }
  
  QTabWidget:movable {
      background: #ff7500;
  }
  
  QTabBar::tab {
      background: #535a57;
      min-width: 8ex;
      padding: 5px 10px;
  }
  
      QTabBar::tab:hover {
          background: #6fc2ff;
      }
  
      QTabBar::tab:movable {
          background: #ff7500;
      }
  
      QTabBar::tab:selected {
          background: #0094ff;
      }
  
      QTabBar::tab:!selected {
          margin-top: 5px;
      }
  </code></pre>
  
  <p>I'm not sure if I'm covering all of the possible states, but I don't know which states the <code>::tab</code> subcontrol has. Thanks for your time looking at this!</p>
