I don't remember doing this.

I think back when I started to kick the tires on Haystack2 I ran into this and made this commit, but never followed through with a PR. Unfortunately I can't remember if that's because there's a problem with the fix, or what. Need to take a closer look before submitting a PR back to the main project.
