@jggautier yes, good catch. I left some comments on #9546. This PR fixes it so I added "closes #9546" to the description of this PR for the issue to get auto-closed on merge.

@ffritze thank for the pull request! This actually fixes an existing issue:

I went ahead and marked this PR as closing it and left some comments in it.

I'm close to approving this PR but please see my comments in this review. Thanks again!

@pdurbin I have added two test functions and added the the release note snippet. So eventually we are ready for the merge?
