Unit test coverage gap when running 3.14 #2446
Description
I'm hitting a strange issue where there is a coverage gap in python 3.14 in unit tests, but in all other python runtimes there is no gap. See https://github.com/googleapis/gapic-generator-python/actions/runs/18045136023/job/51353943485?pr=2344
