Created attachment 247129 [details] Example output It correctly lists "Media: screen, projection" for a style rule, but then links to 'src:1' which is useless. I'm not sure what this source location is supposed to be- is it the location of the media query in the CSS file?

yes, it should be the location of the media query in the source.
In this case it should be line src:42 where the link tag is in the HTML. <link href="css/shaders.css" media="screen, projection" rel="stylesheet" type="text/css" /> Seems like this bug is specific to the <link> tag, and like the <style> tag too.
The new styles sidebar no longer displayed the location of the media query.
