Discussion in https://chat.google.com/room/AAAA49vo02s/fAKok131h5c (limited access), although VCR logs are likely to go stale. This can be observed in TestAccContainerCluster_withResourceUsageExportConfig although the underlying test doesn't need the setting so it will still pass. TestAccSdkProvider_billing_project__GOOGLE_CLOUD_QUOTA_PROJECT_environment_variable_interferes_with_the_billing_account_value_used and TestAccSdkProvider_billing_project__using_billing_account_alone_doesn't_impact_provisioning,_but_using_together_with_user_project_override_does are affected (and faster to run) but are currently skipped in VCR.

Root cause from @SarahFrench in GoogleCloudPlatform/magic-modules#11610 (comment):

When the test runs in VCR mode the unaliased provider is the first to be configured, so its Config struct is cached. Later when the aliased provider is used in the test the provider arguments are effectively ignored because the aliased provider pulls in the Config of the un-aliased provider (which was configured with different arguments).
