Modal close animation not working

The 22 August 2015 patch in #3 to modal.js applied cleanly to the latest ctools 7.x-1.x-dev and if still applicable needs to be reviewed.

Checking patch js/modal.js...
Hunk #1 succeeded at 591 (offset 4 lines).
Applied patch js/modal.js cleanly.

Thanks I've committed a variation of this and left in the $(oldFocus).focus();
