Hi @tjohnn, thank you for reaching out. This looks like a duplicate of issue #6934. According to our engineers, this has been resolved in #6940 and will be included in the next release.

That said, I'll be closing this issue now. Let me know if there's any misunderstanding so we can re-open the issue. Thanks!
