* This file just picks one case where browsers are supposed to throw an
* exception, and tests the heck out of whether it meets the spec. In the
* future, all these checks should be in assert_throws_dom(), but we don't want
* every browser failing every assert_throws_dom() check until they fix every
* single bug in their exception-throwing.
*
* We don't go out of our way to test everything that's already tested by
* interfaces.html, like whether all constants are present on the object, but
* some things are duplicated.
