DomainManger is not updating TLS to 1.2

[ghost]

I have Domain Manger updated to "serverless-domain-manager": "^4.2.0" and added TLS to my serverless config like

customDomain:
    domainName: 'DOMAIN'
    basePath: 'PATH'
    stage: STAGE
    certificateName: 'CERTIFICATE'
    createRoute53Record: true
    endpointType: 'regional'
++  securityPolicy: tls_1_2

so when I deploy my API Gateway I will get these here:
Serverless: Custom domain XXXX already exists.
and its still TLS 1.0

Problem still exists in version 5.2.0.

Interestingly, I do see this in the output:

Serverless Domain Manager: Info: Updated API mapping from '' to '(none)' for <my-domain>

so I know it can update some things, anyway.

This sounds similar or the same:
#516
