Microsoft CA certificate on F5 not using Common Name

Good Morning,

We are using F5OS 1.2 with the 15.1.6.1-0.0.10.T4 bundle as a tenant.  We are generating CA certificates from our local Microsoft CA server and have noticed that the F5 / browser certificate when it comes back does not work as excpected.  Anything we put in the Common Name field is ignored and it only looks at the SAN fields.  If I put in a shortname or FQDN in Common for tenant, appliance or partition / application SSL certificate the browsers we tried it on just fail repeatedly.  If I put either shortname or FQDN in Common for tenant, appliance or partition / application SSL certificate the browsers are happy and show us the happy green lock.  Our support staff reports that the Common field works in version 14 but I cannot find a bug report or issue tracking ticket that shows that it might be broken in version 15 of the tenant bundle.
