If someone adds italics to a comment, the rest of the page becomes italic.
People are doing this kind of mark-up:
When I view source, it's showing this instead - changing the first
</em>, and removing the close-italics mark-up:
But when I try to edit the comment, the mark-up shows up correctly, as originally typed.
I can't find any other stray code weirdness on the site.
What could be going on here?
