HasOne relationship on Owned type not working as expected with Cosmos

[altick]

I have the one-to-many relationship configured between Membership (owned by Activity entity) and entity User. When I select all activities I get back results where only the first activity's membership contains the instance of the user entity. For the rest of the results the users are set to null.

However when I create all entities and query the activities within the same instance of the context I receive the expected results, i.e. all users are set for all memberships.

This is a snippet of how the relationship between Membership and User is configured:

builder.OwnsMany(a => a.Members)
           .HasOne(m => m.User)
           .WithMany()
           .HasForeignKey(m => m.UserId);

This is a snippet of how the activities are queried:

var activities = context.Activities
                .Include(a => a.Members)
                .ThenInclude(m => m.User)
                .ToArray();

Please, check out the solution with the repro for the further details
