Looks good. Is there a test we can add?
Comment 3 Adam Barth 2010-08-07 13:39:37 PDT 
Probably.  You just need to grab an object that has this method and then remove the <html> element from the document, and then call the method.

Here's the repro:

<body onload="document.open();window.styleMedia.matchMedium();">
