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