I looked into changing this in the spec and noticed that this would change
the argument of the callback from the MediaQueryList object to the event,
which is potentially a Web compat problem.
For instance http://www.cafepress.ca/ uses:
cafepress.globalHeader.matchMedia(570, function(mq){
if(!gtmLoaded) {
if(!mq || !mq.matches) {
This can be solved by minting a new event interface that has .media and
.matches.
It would still break if a page uses e.g. removeListener on the callback's
argument, or does other things like type-check the argument, but maybe
that's not common enough to worry about.
