Thanks for the report. We have a couple of blocking PRs to get to first, but I will look into this as soon as I can.

I tried to reproduce and so far things are working as expected. I moved the issue over to the tutorial's repo. I'm subscribed to the new issue, so I'll be watching to see if something needs to be done in this repo.
