Is this easily reproducible? It didn't happen on my build.
Would it be possible to get a pernosco link?

Comment 2

[Tyson Smith [:tsmith]]

No sorry I was unable to reproduce the issue myself. Feel free to close the issue if it is not actionable. If a new link comes in that is reliable I can re-open and add a Pernosco session.
