title: Sectionlist Horizontal with sticky header in React Native?
body: <p>I've been able to render the Sectionlist in React Native with horizontal={true}, but when I have two problems with the section header.</p>
  
  <ol>
  <li>The header appears as a part of the list, and not above it.</li>
  <li>Even with stickySectionHeadersEnabled={true}, the header does not stick and scrolls along with the list.</li>
  </ol>
