Does Roots generate the .bypostauthor class?

I’m not seeing the .bypostauthor class in the comments. I’m digging around for how to add it, but was wondering if it might be something to add support for in Roots? Anyone else added this in manually?

Ah. This is working now. I was adding comments without being logged in, but using the same email as the WordPress user. Apparently that’s not enough to trigger the class. You can delete this thread if you want.
