Hi @plummercj , thank you for the review and comments. I've updated the PR and will run the required tests on linux-x64. I currently don't have access to the other platforms (linux-aarch64, macosx-x64, macosx-aarch64, windows-x64), so I'd appreciate it if you could help run the patch through your CI .
