Create domain command not updating security policy to use minimum TLS version specified

Question
Create domain command not updating security policy to use minimum TLS version specified

Command Run
serverless create_domain

Issue Description
As per the AWS docs we can specify the security policy parameter to use the minimum TLS version given in it. If I update my domain using AWS CLI and check in here then TLS 1.0 and TLS1.1 show as disabled. But when I perform the same thing using the serverless create domain command, it has no effect on enforcing the minimum TLS version. It does update the TLS to 1.2 but TLS 1.0 and 1.1 is still enabled.

Domain Manager Configuration

  customDomain:
    domainName: ${self:custom.config.environment.domain}
    basePath: 'v1'
    stage: ${self:custom.config.environment.envRuntime}

    certificateName: ${self:custom.config.environment.certificate}
    endpointType: 'regional'
    securityPolicy: tls_1_2
