Preloaded association goes away when replacing with Omit

GORM Playground Link

The issue is so trivial that (I think) a playground link is not required here.

The issue: Preloaded association goes away when replacing association with Omit('associationName.*')

For ex:

user := new(model.User)

// get user with groups
database.DB.Preload("Groups").Find(&user, userId)

// then create new groups for the user
groups := new([]model.Group)
// ... add group  like model.Group{ID: 1}

//Replace groups to sync with the selection, Also make sure if non-existing groups are provided, not to create them.
database.DB.Model(&user).Omit("Groups.*").Association("Groups").Replace(groups)

// now user.groups is gone
fmt.Printf("%#v", user.groups)

// following is the output
[]model.Group{
  model.Group{
      ID:0x1, // has only the id
      Name:"", 
      Description:"", 
      //... all empty
  }
}
