I am pretty certain that `jsObjectForPlugin` is not the value you want.

This parameter is supposed to identify the *scope* object that you're 
evaluating against. In almost all cases, you should be passing `window` 
as your scope object, and I'm certain that's what you want in this case.

I'm not sure why we allow you to specify other scope objects, or whether 
we should just ignore the scope parameter because `window` is always 
correct.

I'm also interested in figuring out why this used to work but doesn't 
any more; I'll try to look at this.
