When a base model has a $connection property and a child model sets its own connection with the #[Connection] attribute, the attribute just gets ignored and the child still uses the parent's connection:

abstract class BaseModel extends Model
{
    protected $connection = 'mysql';
}

#[Connection('reporting')]
class SalesReport extends BaseModel {}

(new SalesReport)->getConnectionName(); // 'mysql' instead of 'reporting'

No error, the queries just go to the wrong database. It's an easy one to run into when switching to attributes bit by bit, since the base model usually keeps the old property.
