UPS not resolving group membership for domain group

I have two trusted domains A and B in a single forest. We have an AD group groupA in domain A that contains users from both domain A and domain B. SharePoint is installed in domain A. However, after UPS is run, when looking at the the group in the audience setting, you see that the membership count only reflects the members of domain A but not in domain B. The AD permissions for Directory replication is set correctly.

So in summary-

1. Domain A and Domain B (Full Trust)
2. SharePoint in Domain A
3. GroupA in Domain A with 5 users from Domain A and 12 users from Domain B
4. Post UPS import in audience setup, group only shows membership count as 5 instead of 17
5. Users from both Domain A and Domain B show up in the User Profiles

Is this a known limitation? or is something wrong?
