LGTM.
Normally, I think it is preferred to keep library updates separate from bugfixes, just to avoid any confusion in the case where one may impact the other. In this particular case it's probably OK to have both in one PR.

And, as a side note (not for this PR), can I please encourage you to add unit tests to this integration as well as to your third-party library? That may have detected some of the issues you are fixing now. Thanks.

Thanks @exxamalte, this is a good point. I've started adding tests to the library, and I'll work on adding them to the integration as well.
