When logged in Facebook I get a popup when choosing to see comments (not on all Facebook-pages but on some - see below). This new behaviour is not supported in archiveweb.page and the AutoPilot-function doens´t work. Earlier the comments just expanded downwards - thus being crawled fine with AutoPilot in many cases. I checked with co-workers and they didn´t have the same experience in Facebook.
