It looks like the macOS 12.4 test is failing but the failing test does not appear to be related to my change. Are these known flaky tests? If so, could someone with permission re-run the failed jobs?

[brentleyjones]

Yes. #715 will make the 12.4 ones not fail.

[cgrindel]

I just rebased with the fix for #715. When someone gets a chance, could they approve the workflow? Thanks!
