Need advice on this guys,

I have a Blueprint Page (/content/mysite/master/en/testpage) and Live Copy (/content/mysite/us/en/testpage).
I gated the Blueprint page by enabling "Authentication Requirement". Behind the scene it's adding  jcr:mixinTypes property with value granite:AuthenticationRequired. When this page is rolledout the Live Copy is not receiving this jcr property.
Regular content changes are reflecting though.

I tried updating "WCM Rollout Manager" config with "jcr:(?!(mixinTypes)$).*" but still "jcr:mixinTypes" property is still not rolling out to Live copy.

+Rollout Manager config:
