The test suite contains a test that asserts that an exception should be
thrown when no arguments are passed to querySelector or querySelectorAll.
Why is passing no parameter to querySelector/querySelectorAll expected to
throw an exception, whereas passing an undefined value does not?

The Selectors API specification mentions explicit undefineds being passed
(and says, via Web IDL, that they stringify to "undefined") - that's fine,
but I cannot find the rules that govern omitted attributes.  Presumably Web
IDL must say something somewhere that's overridding the default ECMAScript
rules on this sort of thing - but where precisely?

Taking the null, explicit undefined and implicit undefined test cases
together, I don't think I've got any two browsers here that behave the same
way. :-/
