Hi Gordon et al.,
The formatting for my Jmatches are being misapplied a little in moodle 2.8. (See attached images, one with the hotpot-html in moodle and one as I was hoping to see it.)
(The file is html that I've added added a minimum height to so that the matched items are the same on both left and right. Note also the floating little box at the top, to which is pointing one of the arrows.)
