Alright, it's a common sight on the wiki. Autofire cards seem to mess up the formatting of the card directly afterward. It can turn into a cascade of broken cards.
I have found the problem! Apparently, if the card's cell… The box around it… If it is not larger than the card image, that is what breaks things. Spacing out the elements fixes the problem entirely. I suspected this might be the problem when I noticed that simply clicking the link to expand the card fixed the formatting temporarily.
So now we know.
