Some images' tags in description aren't self closing

In the description field, some <img> tags have no forward slash at the end.

This is an example from the description of Barry Allen character using the API.

<img alt=\"The Flash!\" src=\"data:image/gif;base64,R0lGODlhAQABAAAAACH5BAEKAAEALAAAAAABAAEAAAICTAEAOw==\" sizes=\"(max-width: 417px) 100vw, 417px\" data-width=\"417\" class=\"js-lazy-load-image\" data-src=\"https://comicvine1.cbsistatic.com/uploads/original/0/5634/134903-62343-barry-allen.jpg\" data-srcset=\"https://comicvine1.cbsistatic.com/uploads/original/0/5634/134903-62343-barry-allen.jpg 326w\">

img element in HTML doesn't have an end tag. So <img src="xx.jpg" alt="" > is correct markup. XHTML does but the markup here is just vanilla HTML.
