<p>start</p>
<a href=#contents" id="disappearingObject" style="position: static">
  hello world
  </a>
<script>
  var toggle = false;
  setInterval(function() {
    document.getElementById('disappearingObject').style.position = toggle ? 'static' : 'absolute';
    toggle = !toggle;
  }, 1000);
  </script>

expected:
disappearingObject should retain its accessibility id

result:
disappearingObject keeps on receiving a new accessibility id
