Serverless logs with --tail does not work

[HyperBrain]

Serverless logs in general works to print the CW logs of an aliased function version.
Nevertheless, when you try to use --tail it just prints the same information as without the option and exits.

The expected behavior would be, that Serverless keeps running and prints new log events periodically.
Additionally there is a crash, if you specify the -i option to set an interval, but omit the value.
