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