I've got Jetpack's comments setup on my site, and though they are working in general in that people can comment and connect to social media accounts, I'm having a problem with the Reply button. When clicking the Reply button, the expected behaviour is that the reply box will move to underneath the comment on which Reply was clicked. I'm getting a specific error in the Firebug console, stating:
jetpack Uncaught ReferenceError: addComment is not defined. I can see addComment in the page source, and I don't see any other JS errors before it that would cause it to not function.

I do have W3TC installed, but minify is turned off entirely.
