@jakergrossman Thanks for the PR! To my understanding, PRs affecting core QMK code are "breaking changes" and are required to merge into the develop branch instead of master. Are you able to repoint it? The GH doc page Changing the base branch of a pull request says there might be a dropdown menu at the top of the page where it says "jakergrossman wants to merge 1 commit into qmk:master" to select the destination branch.

@getreuer I see. I've repointed it at develop, thanks!
