Well, I have no idea how to reduce it further because for one, I don't know how to cause this issue otherwise, second, I can't reproduce the issue when including chuck.js in a static Web page. The error only occurs for me when I include chuck.js in a SPA (I first encountered it within a Meteor application, so my current app is simpler).
