append() leaking objects into the global namespace

[[email protected]…]

On webkit browsers (i tested current chrome and safari on os x 10.8.4), save ​http://pastebin.com/8i1KtAHT as an html file and load. you'll see in the webkit console output that the variable "id" is being leaked into the global namespace by the $.append() function.

Note that item, refundAmount, and refundCurrency also "leak", even if you reimplement with .innerHTML instead of jQuery. Webkit, like many browser engines, defines properties on the global object (window) to access elements with ids.
