Nested createMany with skipDuplicates option is not handled correctly

[ymc9]

ZModel

model User {
  id String @id @default(cuid())
  companies CompanyUser[]
  @@allow('all', true)
}
            
model Company {
  id String @id @default(cuid())
  users CompanyUser[]
  @@allow('all', true)
}
            
model CompanyUser {
  company Company @relation(fields: [companyId], references: [id], onDelete: Cascade)
  companyId String
  user User @relation(fields: [userId], references: [id], onDelete: Cascade)
  userId String
  @@id([companyId, userId])
  @@allow('all', true)
}

Code

const db = enhance(prisma);
await db.user.create({ data: { id: 'abc' } });
await db.user.create({ data: { id: 'def' } });
await db.company.create({ data: { id: '1', users: { create: { userId: 'abc' } } } });
await db.company.update({
     where: { id: '1' },
     data: {
       users: {
         createMany: {
           data: [{ userId: 'abc' }, { userId: 'def' }],
           skipDuplicates: true,
         },
       },
     },
     include: { users: true },
})

The code should succeed but it results in unique constraint violation error.
