Blackfriday renders links that are not links


Wondering if anyone has seen this with BlackFriday:

This Markdown copy (note that there’s a space between the closing bracket and open parenthesis):

This is [not] (a link)

renders as:

This is <a href="a link">not</a>

which, is incorrect. It should render as it’s written.

I can escape the closing bracket to eliminate the link, but that seems incorrect to me. Does anyone know if this is expected behavior, or if there is a setting to turn it off?
