Misunderstanding of shortcode syntax in 0.55

If you have markdown headings in the .Inner and you want them to show up in a table of contents you can try something like this:

## Heading

 {{ printf "<div clas=\"markdownify\">" | htmlUnescape | safeHTML }}
    {{ .Inner }}
 {{ printf "</div>" | htmlUnescape | safeHTML }}

Thank you @zwbetz for this work around.
