Specifying --password "secret" --password in client asks user to enter password

[Demilivor]

ClickHouse client version 23.5.1.1

Describe the unexpected behavior.
Specifying --password "secret" --password asks the user to enter the password instead of failing in the console output.

Repro
clickhouse-client --password "secret" --password

Expected behavior
An error: Bad arguments: option '--password' cannot be specified more than once

Error message and/or stacktrace
No error message. The client just ignores the "secret" password, and uses implicit_value "" from the boost options configuration.
If the password is an empty string, then the client asks the user to enter the password (even if the user does not have a password).
