This is a great feature and I’m using it right now, but I think that if we use it on a given page, then the comments shouldn’t be rendered again.
Right now, using the do_action PHP code, I’m getting the comments box 2 times, so I added a boolean in the FBComments class that checks if the comments box has been already rendered – if false, renders it, if true, don’t render.
Maybe there’s a more elegant way to do this, but it worked for me without much hassle.
