BF-40958 is a BF that has occurred due to FailedToSatisfyReadPreference errors in config_shard_catalog_cache_refresh.js in the sharding_csrs_continuous_config_stepdown suite. 

The test heavily relies on the readPreference to target the Primary, which is made very difficult if there are constant stepdowns. Since the test relies on a stable topology, it should not run in a suite where there are constant stepdowns.
