Auto merge of #8854 - KiChjang:undefined-as-missing, r=frewsxcv

Browse source 
Treat 'undefined' passed to optional JS arguments as missing

@frewsxcv please don't hurt me for this.

I've added an AND condition to check whether the value being passed is undefined while checking whether the argument exists at all. Essentially, this is now treating undefined arguments the same as missing arguments.

Fixes #8813.
Fixes #6558.
