Hugo does not regognize markdown inside border

[Steve_J]

I do have this code

{{< border >}}
* A  
* B  
* C  
* D
{{< /border >}}

I would expect to see a list rendered, but instead its just displayed as it is
Any ideas how to fix?

I am using this theme Papercss Hugo Theme | Hugo Themes

Use {{% border %}} for shortcodes that return markdown.
