title: Facebook yoga/react-native flexbox css-layout position: "fixed" support
body: <p>For support of position: "fixed" in css-layout(react-native),</p>
  
  <p><strong>Use case:</strong> I have (many) videoView deeply nested in view hierarchy - think list of videos,
  any one of which I want to make fullscreen.</p>
  
  <p><strong>Current approach (hack):</strong>
  make videoview as big as screen(fixed values for height width in css style),
  track videoview's parent layout position and give negative margins to videview to show it properly.</p>
  
  <p><strong>Desired approach:</strong> Was wondering if there is a simple way to do this
  (like <code>position: fixed</code>)</p>
  
  <p>Any suggestions or help is welcome</p>
