It's the behavior in Firefox and Opera too.

In both cases below, the audio is paused when removed from the document.  
When added back it's still paused and when you call play(), it continues  
playing from where it left off.

             window.addEventListener("DOMContentLoaded", function() {
                 var player = document.createElement("audio");
                 player.controls = true;
                 player.autoplay = true;
                 player.src = "test.oga";
                 document.body.appendChild(player);
                 setTimeout(function() {
                     document.body.removeChild(player);
                     setTimeout(function() {
                         document.body.appendChild(player);
                         player.play();
                     }, 3000);
                 }, 7000);
             }, false);
         </script>
