title: TinyMCE 5 color_map setting not showing custom colors
body: <p>I need to customize the colors inside TinyMCE 5 color pickers. In the documentation I have found:</p>
  
  <p><a href="https://www.tiny.cloud/docs/configure/content-appearance/#color_map" rel="nofollow noreferrer">color_map</a></p>
  
  <p>but I cannot make it work:</p>
  
  <pre><code>tinymce.init({
              selector: '#textarea_id',
              height: 500,
              menubar: true,
              relative_urls : false,
              remove_script_host : false,
              plugins: [
                  'advlist autolink lists link image charmap print preview anchor textcolor colorpicker',
                  'searchreplace visualblocks code fullscreen',
                  'insertdatetime media table contextmenu paste code'
              ],
              toolbar: 'undo redo | insert | styleselect | bold italic | strikethrough forecolor backcolor | alignleft aligncenter alignright alignjustify | bullist numlist outdent indent | link paste',
              style_formats: [
  
                  { title: 'Badge', inline: 'span', styles: { display: 'inline-block', border: '1px solid #2276d2', 'border-radius': '5px', padding: '2px 5px', margin: '0 2px', color: '#2276d2' } }
  
                ],
              color_map: [
                  "000000", "Black",
                  "993300", "Burnt orange",
                  "333300", "Dark olive"
  
                ],
              paste_as_text: true,
              content_css: '//www.tinymce.com/css/codepen.min.css'
  
          });
  </code></pre>
  
  <p>My expectation is to see a color picker composed of only 3 colors for foreground text color and background text color but instead I see the standard color picker. Why ? </p>
