I am creating a Select object with a dynamic option list. Using JavaScript, when I call add() on the object and only give it one argument, I get a NS_ERROR_XPC_NOT_ENOUGH_ARGS exception. I have to explicitly pass "undefined" as a second argument in order for the script to work in Firefox and IE. Since this is in JavaScript, any missing arguments should automatically be set to "undefined."

Reproducible: Always

Steps to Reproduce:
1. Call document.formObject.selectObject.add(new Option('A new option', 'A new option', false, false))
Actual Results:  
A NS_ERROR_XPC_NOT_ENOUGH_ARGS exception is thrown, since add() assumes two arguments. I have to explictly set "undefined" to the second argument

Expected Results:  
The JavaScript interpreter should be implicitly passing "undefined" to the second argument.

Since this is currently on an internal business system, I cannot supply a URL. I will attach a test case.
