I was able to find a couple of references to the bug that were reported
downstream.

https://github.com/d12frosted/homebrew-emacs-plus/issues/112

Your patch does indeed fix the bug for me! It also explains why this

added a little over a year ago. I'm a bit shocked at how quickly my bug
report reached someone intimately familiar with the underlying code.
