I noticed that the Google module passes test strings to the onReady method as well, but it looks like the other side of the onready method at https://github.com/typekit/webfontloader/blob/ca93ac059152f5d665451cac03d3f3580f88160b/src/core/webfont.js#L80 doesn't support receiving them. Is this just an oversight? A bug from longer ago? Am I missing something?
