issue with divs

[TheAlexBarth]

When specifying classes on a div, it doesn't render correctly from rmarkdown:

for example, using
:::{.content-visible unless-format='pdf'}

<iframe src='somewebcontent'>

:::

The pdf rendering will have:

:::{.content-visible unless-format='pdf'}
:::

The issue here is that the specific HTML syntax is confusing pandoc. Try closing the iframe tag, either by <iframe src='somewebcontent'/> or by <iframe src='somewebcontent'/></iframe>
