Or at least inline by saying that the UA should use the initial value of those properties. This is a really icky way of writing requirements. 107434 4 annevk 2014-06-06 11:27:04 +0000 Also, the event is exposed on workers, but is the API itself? 107504 5 zcorpan 2014-06-09 08:07:53 +0000 Which properties do you mean? .media and .matched are set to concept-MediaQueryList-media and concept-MediaQueryList-matched. The API isn't exposed to workers currently, but there's a bug asking for that. I guess I can hide the event from workers until then to not confuse feature detection. 107505 6 annevk 2014-06-09 08:16:32 +0000 The methods are defined as directly invoking addEventListener(). (Also, the rationale for changing this API seems rather sketchy. Making the semantics equivalent to events seems reasonable, but exposing this as events, not so much.) 107513 7 zcorpan 2014-06-09 10:01:24 +0000 Thanks https://dvcs.w3.org/hg/csswg/rev/d9c86e52f02a Please reopen or send email to www-style if you care about not exposing the event.
