I added 'fix:' to the beginning of the message, but left the ', fixes #36340' at the end of the description, since it felt informative and I didn't find anything in https://www.conventionalcommits.org/en/v1.0.0/ about how to use closing keywords. But let me know if you want that removed or changed as well.
