User group policies applying from another domain

I've come across an interesting issue:

Domain A and domain B are in different forests and between them is external trust.

Workstation1 is in domain A. User1 account is in domain B.

When User1 logs onto Workstatsion1, it gets all the user policies from Domain A but nothing from domain B as it should.

My questions are:

why is this situation happening?

how to fix this so User1 policies would apply domain B policies, when it logs onto workstation1?

    Workstation1 is in domain A (trusting forest). User1 account is in domain B (trusted forest).
    Based on my understanding, when User1 logs onto Workstation 1, it will get all the computer policies from Domain A but nothing from domain B as it should.

    If you want the user1 apply policies from domain B when logon to Workstation 1, the policy Allow cross-forest user policy and roaming user profiles should be enabled in domain A.

    I also did a test in my lab, for your reference:
