I was wondering if that was intentional. WebKit/Blink/Gecko all treat null as empty string when setting mediaText, at least. http://dev.w3.org/csswg/cssom/#the-medialist-interface [[ interface MediaList { stringifier attribute DOMString mediaText; readonly attribute unsigned long length; getter DOMString item(unsigned long index); void appendMedium(DOMString medium); void deleteMedium(DOMString medium); }; ]] 88902 1 rune 2013-06-07 12:46:35 +0000 (In reply to comment #0) > The MediaList interface contains no TreatNullAs for any of the DOMStrings.

But undefined is stringified as "undefined" and becomes a media type. 88992 2 zcorpan 2013-06-10 13:57:16 +0000 https://dvcs.w3.org/hg/csswg/rev/0b537683d8a3
