Relevant spec text:

http://www.w3.org/html/wg/drafts/html/master/infrastructure.html#safe-passing-of-structured-data

If input is an Array object
   Let output be a newly constructed empty Array object whose length is equal to the length of input.

   This means that the length of sparse arrays is preserved.
