Description list bug

The WHATWG HTML Living Standard says:

"In order to annotate groups with microdata attributes, or other global attributes that apply to whole groups, or just for styling purposes, each group in a element can be wrapped in a   element. This does not change the semantics of the   element. HTML Living Standard § 4.4.9 The   element"

On FANDOM wikis however,  and   tags are automatically closed when they're wrapped in a   tag. This results in duplicate closing tags, which are then interpreted as plain text.

The bug occurs when wikitext for a given page is parsed, so the only way to avoid it is to omit the closing tags. Fortunately, the spec allows omitting and , so this is valid in HTML5.
