Thanks for your PR.

However, as discussed in issue #748, this repo has been unmaintained for several years.
In order to continue this great project started by tfussell, we have created a new repo to support further development by the community.
Feel free to participate in this community effort by submitting issues and PR to this new community-driven repo.

I strongly advise you to try out the community version. I think this issue is already fixed there.
