Markdown Not Converting to HTML Inside a List

[jwalkerinterpres]

It seems like this library doesn't work if the markdown is inside a list. For instance, in this markdown:

Here is a list of your top stuff:
    
    1. ::span[(T1078)]
    2. other stuff
 ::span[(T1078)]

The string ::span[(T1078)] will convert properly, but 1. ::span[(T1078)] will not convert.

Is there any way to use this library with lists, or are the two mutually incompatible?

EDIT: This is with a React Markdown setup like:

<Markdown
        components={{
          span: props => {
            const { node, ...rest } = props;
            return <span style={{ marginTop: '1em' }} {...rest} />;
          }
        }}
        remarkPlugins={[remarkDirective, remarkDirectiveRehype]}
      >
        {markdownText}
 </Markdown>
