sorry for all the force pushes, between the CLA author rewrites to travis tooling...I was just moving too quick I guess 🤷

Anyways, I was experiencing this bug and patched it locally so I could get it working for myself. it works great with this patch. could I get a review on this?

@ak239 et al, could one of you guys take a look at this and approve it. it's blocking some stuff i'm working on and I think it's a worthy contribution to the tool.
