/** Test for Bug 377947 **/
/*
* In particular, test that CSSStyleDeclaration.getPropertyValue doesn't
* return values for shorthands when some of the subproperties are not
* specified (a change that wasn't all that related to the main point of
* the bug). And also test that the internal system-font property added
* in bug 377947 doesn't interfere with that.
