JS object leak test case

I've attached a test case which demonstrates this leak on the most basic level.
It seems like there are a few key things that need to happen in order to cause
the leak:

1. Declare a function-object.
2. In the function object, declare a handler which does something with the
document object.
3. Allocate further memory in the function object to make the leak detectable.
4. Set a variable equal to document, and then run addEventListener on that
variable, attaching the handler to "keydown".
5. Then create a new instance of your function object.

The attached html file will leak approximately 4mb per refresh (or 43 JS
objects if you're monitoring the caches window.
