We're in the middle of looking at a list of matching longhands; should any missing longhand property cause the entire getPropertyValue algorithm to return the empty string? 116191 1 dbaron 2014-12-12 00:20:19 +0000 That's correct; if you're asked for a shorthand, and not all of its subproperties are set, the result is the empty string. 116200 2 zcorpan 2014-12-12 06:15:43 +0000 Yes. Would a note help? 116218 3 josh 2014-12-12 15:16:36 +0000 Yes.
