I think the problem is that point is before the invisible text rather than on the first visible character where it ought to be. Move that window upward with mouse-1. No problem until we hit that same spot with the invisible text. There Emacs goes in an infinite loop, apparently in the C code. C-g is no help. Someone needs to debug it. etc/DEBUG gives advice on how to debug a case of looping usefully.
