Hi Justine, Thanks for reporting this issue. Sounds like a regression in 3.0. Therefore, it would make sense to try to address it before we release 3.0.0.
I marked the jira issue as a Blocker targeting 3.0. Hopefully your PR will fix the issue but let me know if we need to make further adjustments.
